Release Information

Command introduced before Junos OS Release 7.4.

topology option introduced in Junos OS Release 9.0.

realm option introduced in Junos OS Release 9.2.

Description

Display the entries in the Open Shortest Path First (OSPF) routing table.

Options

none—Display standard information about all entries in the OSPF routing table for all routing instances and all topologies.
destination—Display routes to the specified IP address (with optional destination prefix length).
brief | detail | extensive—(Optional) Display the specified level of output.
abr—(Optional) Display routes to area border routers.
asbr—(Optional) Display routes to autonomous system border routers.
extern—(Optional) Display external routes.
inter—(Optional) Display interarea routes.
intra—(Optional) Display intra-area routes.
instance (default | ipv4-multicast | instance-name)—(Optional) Display entries for the default routing instance, the IPv4 multicast routing instance, or for the specified routing instance.
logical-system (default | ipv4-multicast | logical-system-name)—(Optional) Perform this operation on the default logical system, the IPv4 multicast logical system, or on a particular logical system.
network—(Optional) Display routes to networks.

no-backup-coverage—(Optional) Display routes with no backup coverage.
realm (ipv4-multicast | ipv4-unicast | ipv6-multicast)—(OSPFv3 only) (Optional) Display entries in the routing table for the specified OSPFv3 realm, or address family. Use the realm option to specify an address family for OSPFv3 other than IPv6 unicast, which is the default.
router—(Optional) Display routes to all routers.

topology (default | ipv4-multicast | topology-name)—(OSPFv2 only) (Optional) Display routes for the default OSPF topology, IPv4 multicast topology, or for a particular topology.
transit—(Optional) (OSPFv3 only) Display OSPFv3 routes to pseudonodes.

Output Fields

Table 1 list the output fields for the show (ospf | ospf3) route command. Output fields are listed in the approximate order in which they appear.

Table 1: show (ospf | ospf3) route Output Fields

Field Name

Field Description

Output Level

Topology

Name of the topology.

All levels

Prefix

Destination of the route.

All levels

Path type

How the route was learned:

  • Inter—Interarea route

  • Ext1—External type 1 route

  • Ext2—External type 2 route

  • Intra—Intra-area route

All levels

Route type

The type of routing device from which the route was learned:

  • AS BR—Route to AS border router.

  • Area BR—Route to area border router.

  • Area/AS BR—Route to router that is both an Area BR and AS BR.

  • Network—Network router.

  • Router—Route to a router that is neither an Area BR nor an AS BR.

  • Transit—(OSPFv3 only) Route to a pseudonode representing a transit network, LAN, or nonbroadcast multiaccess (NBMA) link.

  • Discard—Route to a summary discard.

All levels

NH Type

Next-hop type: LSP or IP.

All levels

Metric

Route's metric value.

All levels

NH-interface

(OSPFv3 only) Interface through which the route's next hop is reachable.

All levels

NH-addr

(OSPFv3 only) IPv6 address of the next hop.

All levels

NextHop Interface

(OSPFv2 only) Interface through which the route's next hop is reachable.

All levels

Nexthop addr/label

(OSPFv2 only) If the NH Type is IP, then it is the address of the next hop. If the NH Type is LSP, then it is the name of the label-switched path.

All levels

Area

Area ID of the route.

detail

Origin

Router from which the route was learned.

detail

Type 7

Route was learned through a not-so-stubby area (NSSA) link-state advertisement (LSA).

detail

P-bit

Route was learned through NSSA LSA and the propagate bit was set.

detail

Fwd NZ

Forwarding address is nonzero. Fwd NZ is only displayed if the route is learned through an NSSA LSA.

detail

optional-capability

Optional capabilities propagated in the router LSA. This field is in the output for intra-area router routes only (when Route Type is Area BR, AS BR, Area/AS BR, or Router), not for interarea router routes or network routes. Three bits in this field are defined as follows:

  • 0x4 (V)—Routing device is at the end of a virtual active link.

  • 0x2 (E)—Routing device is an autonomous system boundary router.

  • 0x1 (B)—Routing device is an area border router.

detail

priority

The priority assigned to the prefix:

  • high

  • medium

  • low

Note: The priority field applies only to routes of type Network.

detail

BGP-ORR Generation-ID

Display the BGP-ORR generation identifier of the main OSPF route. This field is shown only for non-zero values.
