Table 1: show route detail Output Fields

Field Name

Field Description


Name of the routing table (for example, inet.0).

number destinations

Number of destinations for which there are routes in the routing table.

number routes

Number of routes in the routing table and total number of routes in the following states:

  • active (routes that are active)

  • holddown (routes that are in the pending state before being declared inactive)

  • hidden (routes that are not used because of a routing policy)

route-destination (entry, announced)

Route destination (for example: The entry value is the number of routes for this destination, and the announced value is the number of routes being announced for this destination. Sometimes the route destination is presented in another format, such as:

  • MPLS-label (for example, 80001).

  • interface-name (for example, ge-1/0/2).

  • neighbor-address:control-word-status:encapsulation type:vc-id:source (Layer 2 circuit only; for example,

    • neighbor-address—Address of the neighbor.

    • control-word-status—Whether the use of the control word has been negotiated for this virtual circuit: NoCtrlWord or CtrlWord.

    • encapsulation type—Type of encapsulation, represented by a number: (1) Frame Relay DLCI, (2) ATM AAL5 VCC transport, (3) ATM transparent cell transport, (4) Ethernet, (5) VLAN Ethernet, (6) HDLC, (7) PPP, (8) ATM VCC cell transport, (10) ATM VPC cell transport.

    • vc-id—Virtual circuit identifier.

    • source—Source of the advertisement: Local or Remote.

    • source—Source of the advertisement: Local or Remote.

label stacking

( Next-to-the-last-hop routing device for MPLS only) Depth of the MPLS label stack, where the label-popping operation is needed to remove one or more labels from the top of the stack. A pair of routes is displayed, because the pop operation is performed only when the stack depth is two or more labels.

  • S=0 route indicates that a packet with an incoming label stack depth of 2 or more exits this routing device with one fewer label (the label-popping operation is performed).

  • If there is no S= information, the route is a normal MPLS route, which has a stack depth of 1 (the label-popping operation is not performed).

[protocol, preference]

Protocol from which the route was learned and the preference value for the route.

  • +—A plus sign indicates the active route, which is the route installed from the routing table into the forwarding table.

  • - —A hyphen indicates the last active route.

  • *—An asterisk indicates that the route is both the active and the last active route. An asterisk before a to line indicates the best subpath to the route.

In every routing metric except for the BGP LocalPref attribute, a lesser value is preferred. In order to use common comparison routines, Junos OS stores the 1's complement of the LocalPref value in the Preference2 field. For example, if the LocalPref value for Route 1 is 100, the Preference2 value is -101. If the LocalPref value for Route 2 is 155, the Preference2 value is -156. Route 2 is preferred because it has a higher LocalPref value.

Preference2 values are signed integers, that is, Preference2 values can be either positive or negative values. However, Junos OS evaluates Preference2 values as unsigned integers that are represented by positive values. Based on the Preference2 values, Junos OS evaluates a preferred route differently in the following scenarios:

  • Both Signed Preference2 values

    • Route A = -101

    • Route B = -156

    Where both the Preference2 values are signed, Junos OS evaluates only the unsigned value of Preference2 and Route A, which has a lower Preference2 value is preferred.

  • Unsigned Preference2 values

    Now consider both unsigned Preference2 values:

    • Route A = 4294967096

    • Route B = 200

    Here, Junos OS considers the lesser Preference2 value and Route B with a Preference2 value of 200 is preferred because it is less than 4294967096.

  • Combination of signed and unsigned Preference2 values

    When Preference2 values of two routes are compared, and for one route the Preference2 is a signed value, and for the other route it is an unsigned value, Junos OS prefers the route with the positive Preference2 value over the negative Preference2 value. For example, consider the following signed and unsigned Preference2 values:

    • Route A = -200

    • Route B = 200

    In this case, Route B with a Preference2 value of 200 is preferred although this value is greater than -200, because Junos OS evaluates only the unsigned value of the Preference2 value.


(IS-IS only). In IS-IS, a single AS can be divided into smaller groups called areas. Routing between areas is organized hierarchically, allowing a domain to be administratively divided into smaller areas. This organization is accomplished by configuring Level 1 and Level 2 intermediate systems. Level 1 systems route within an area. When the destination is outside an area, they route toward a Level 2 system. Level 2 intermediate systems route between areas and toward other ASs.

Route Distinguisher

IP subnet augmented with a 64-bit prefix.


Provider multicast service interface (MVPN routing table).

Next-hop type

Type of next hop. For a description of possible values for this field, see Table 2.

Next-hop reference count

Number of references made to the next hop.

Flood nexthop branches exceed maximum message

Indicates that the number of flood next-hop branches exceeded the system limit of 32 branches, and only a subset of the flood next-hop branches were installed in the kernel.


IP address of the route source.

Next hop

Network layer address of the directly reachable neighboring system.


Interface used to reach the next hop. If there is more than one interface available to the next hop, the name of the interface that is actually used is followed by the word Selected. This field can also contain the following information:

  • Weight—Value used to distinguish primary, secondary, and fast reroute backup routes. Weight information is available when MPLS label-switched path (LSP) link protection, node-link protection, or fast reroute is enabled, or when the standby state is enabled for secondary paths. A lower weight value is preferred. Among routes with the same weight value, load balancing is possible.

  • Balance—Balance coefficient indicating how traffic of unequal cost is distributed among next hops when a routing device is performing unequal-cost load balancing. This information is available when you enable BGP multipath load balancing.

Label-switched-path lsp-path-name

Name of the LSP used to reach the next hop.

Label operation

MPLS label and operation occurring at this routing device. The operation can be pop (where a label is removed from the top of the stack), push (where another label is added to the label stack), or swap (where a label is replaced by another label).


(Local only) Local interface name.

Protocol next hop

Network layer address of the remote routing device that advertised the prefix. This address is used to derive a forwarding next hop.

Indirect next hop

Index designation used to specify the mapping between protocol next hops, tags, kernel export policy, and the forwarding next hops.


State of the route (a route can be in more than one state). See Table 3.

Local AS

AS number of the local routing device.


How long the route has been known.


Accumulated interior gateway protocol (AIGP) BGP attribute.


Cost value of the indicated route. For routes within an AS, the cost is determined by IGP and the individual protocol metrics. For external routes, destinations, or routing domains, the cost is determined by a preference value.


Metric value for BGP path selection to which the IGP cost to the next-hop destination has been added.


For MPLS LSPs, state of the TTL propagation attribute. Can be enabled or disabled for all RSVP-signaled and LDP-signaled LSPs or for specific VRF routing instances.

For sample output, see show route table .


Name of the protocol that has added the route.

Announcement bits

The number of BGP peers or protocols to which Junos OS has announced this route, followed by the list of the recipients of the announcement. Junos OS can also announce the route to the KRT for installing the route into the Packet Forwarding Engine, to a resolve tree, a L2 VC, or even a VPN. For example, n-Resolve inet indicates that the specified route is used for route resolution for next hops found in the routing table.

  • n—An index used by Juniper Networks customer support only.

AS path

AS path through which the route was learned. The letters at the end of the AS path indicate the path origin, providing an indication of the state of the route at the point at which the AS path originated:

  • I—IGP.

  • E—EGP.

  • Recorded—The AS path is recorded by the sample process (sampled).

  • ?—Incomplete; typically, the AS path was aggregated.

When AS path numbers are included in the route, the format is as follows:

  • [ ]—Brackets enclose the number that precedes the AS path. This number represents the number of ASs present in the AS path, when calculated as defined in RFC 4271. This value is used in the AS-path merge process, as defined in RFC 4893.

  • [ ]—If more than one AS number is configured on the routing device, or if AS path prepending is configured, brackets enclose the local AS number associated with the AS path.

  • { }—Braces enclose AS sets, which are groups of AS numbers in which the order does not matter. A set commonly results from route aggregation. The numbers in each AS set are displayed in ascending order.

  • ( )—Parentheses enclose a confederation.

  • ( [ ] )—Parentheses and brackets enclose a confederation set.


In Junos OS Release 10.3 and later, the AS path field displays an unrecognized attribute and associated hexadecimal value if BGP receives attribute 128 (attribute set) and you have not configured an independent domain in any routing instance.


(BGP-learned routes) Validation status of the route:

  • Invalid—Indicates that the prefix is found, but either the corresponding AS received from the EBGP peer is not the AS that appears in the database, or the prefix length in the BGP update message is longer than the maximum length permitted in the database.

  • Unknown—Indicates that the prefix is not among the prefixes or prefix ranges in the database.

  • Unverified—Indicates that the origin of the prefix is not verified against the database. This is because the database got populated and the validation is not called for in the BGP import policy, although origin validation is enabled, or the origin validation is not enabled for the BGP peers.

  • Valid—Indicates that the prefix and autonomous system pair are found in the database.

ORR Generation-ID

Displays the optimal route reflection (ORR) generation identifier. ISIS and OSPF interior gateway protocol (IGP) updates filed whenever any of the corresponding ORR route has its metric valued changed, or if the ORR route is added or deleted.

FECs bound to route

Point-to-multipoint root address, multicast source address, and multicast group address when multipoint LDP (M-LDP) inband signaling is configured.

Primary Upstream

When multipoint LDP with multicast-only fast reroute (MoFRR) is configured, the primary upstream path. MoFRR transmits a multicast join message from a receiver toward a source on a primary path, while also transmitting a secondary multicast join message from the receiver toward the source on a backup path.

RPF Nexthops

When multipoint LDP with MoFRR is configured, the reverse-path forwarding (RPF) next-hop information. Data packets are received from both the primary path and the secondary paths. The redundant packets are discarded at topology merge points due to the RPF checks.


Multiple MPLS labels are used to control MoFRR stream selection. Each label represents a separate route, but each references the same interface list check. Only the primary label is forwarded while all others are dropped. Multiple interfaces can receive packets using the same label.


Value used to distinguish MoFRR primary and backup routes. A lower weight value is preferred. Among routes with the same weight value, load balancing is possible.

VC Label

MPLS label assigned to the Layer 2 circuit virtual connection.


Maximum transmission unit (MTU) of the Layer 2 circuit.


VLAN identifier of the Layer 2 circuit.

Prefixes bound to route

Forwarding equivalent class (FEC) bound to this route. Applicable only to routes installed by LDP.

Layer 2 encapsulation (for example, VPLS).

control flags

Control flags: none or Site Down.


Maximum transmission unit (MTU) information.

Label-Base, range

First label in a block of labels and label block size. A remote PE routing device uses this first label when sending traffic toward the advertising PE routing device.

status vector

Layer 2 VPN and VPLS network layer reachability information (NLRI).

Accepted Multipath

Current active path when BGP multipath is configured.

Accepted LongLivedStale

The LongLivedStale flag indicates that the route was marked LLGR-stale by this router, as part of the operation of LLGR receiver mode. Either this flag or the LongLivedStaleImport flag may be displayed for a route. Neither of these flags are displayed at the same time as the Stale (ordinary GR stale) flag.

Accepted LongLivedStaleImport

The LongLivedStaleImport flag indicates that the route was marked LLGR-stale when it was received from a peer, or by import policy. Either this flag or the LongLivedStale flag may be displayed for a route. Neither of these flags are displayed at the same time as the Stale (ordinary GR stale) flag.

Accept all received BGP long-lived graceful restart (LLGR) and LLGR stale routes learned from configured neighbors and import into the inet.0 routing table




Accept all received BGP long-lived graceful restart (LLGR) and LLGR stale routes learned from configured neighbors and imported into the inet.0 routing table

The LongLivedStaleImport flag indicates that the route was marked LLGR-stale when it was received from a peer, or by import policy.

The DeletePending flag indicates that a BGP route needs to be processed due to a BGP peer down event.

Accepted MultipathContrib

Path currently contributing to BGP multipath.


Local preference value included in the route.

Table 2: Next-hop Types Output Field Values

Next-Hop Type


Broadcast (bcast)

Broadcast next hop.


Deny next hop.


Discard next hop.

Dynamic List

Dynamic list next hop


Flood next hop. Consists of components called branches, up to a maximum of 32 branches. Each flood next-hop branch sends a copy of the traffic to the forwarding interface. Used by point-to-multipoint RSVP, point-to-multipoint LDP, point-to-multipoint CCC, and multicast.


Next hop is waiting to be resolved into a unicast or multicast type.

Used for a network address assigned to an interface. Unlike the router next hop, the interface next hop does not reference any specific node on the network.

Local (locl)

Local address on an interface. This next-hop type causes packets with this destination address to be received locally.

Multicast (mcst)

Wire multicast next hop (limited to the LAN).

Multicast discard (mdsc)

Multicast discard.

Multicast group (mgrp)

Multicast group member.

Receive (recv)

Discard. An ICMP unreachable message was sent.

Resolve (rslv)

Resolving next hop.

Routed multicast (mcrt)

Regular multicast next hop.


A specific node or set of nodes to which the routing device forwards packets that match the route prefix.

To qualify as next-hop type router, the route must meet the following criteria:

  • Must not be a direct or local subnet for the routing device.

  • Must have a next hop that is directly connected to the routing device.


Next hop added to the Routing Engine forwarding table for remote IP addresses with prefix /32 for Junos OS Evolved only.
