| Route Information
|
|
|
n destinations
|
Number of destinations for which there are routes in the routing table.
|
|
|
n routes
|
Number of routes in the routing table:
-
active—Number of routes that are active.
-
holddown—Number of routes that are in hold-down
state (neither advertised nor updated) before being declared inactive.
-
hidden—Number of routes not used because of routing
policies configured on the Services Router.
|
|
|
Destination
|
Destination address of the route.
|
|
|
Protocol/ Preference
|
Protocol from which the route was learned: Static, Direct, Local,
or the name of a particular protocol.
The preference is the individual preference value for the route.
|
The route preference is used as one of the route selection criteria.
|
|
Next-Hop
|
Network layer address of the directly reachable neighboring system (if
applicable) and the interface used to reach it.
|
If a next hop is listed as Discard, all traffic with that destination
address is discarded rather than routed. This value generally means that the
route is a static route for which the discard attribute has been
set.
If a next hop is listed as Reject, all traffic with that destination
address is rejected. This value generally means that the address is unreachable.
For example, if the address is a configured interface address and the interface
is unavailable, traffic bound for that address is rejected.
If a next hop is listed as Local, the destination is an address
on the host (either the loopback address or the Ethernet management port address,
for example).
|
|
Age
|
How long the route has been known.
|
|
|
State
|
Flags for this route.
|
There are many possible flags. For a complete description, see the JUNOS Routing Protocols and Policies Command Reference.
|
|
AS Path
|
AS path through which the route was learned. The letters of the AS path
indicate the path origin:
- I — IGP.
- E — EGP.
- ? — Incomplete. Typically, the AS path was aggregated.
|
|
| BGP Summary |
|
Groups
|
Number of BGP groups.
|
|
|
Peers
|
Number of BGP peers.
|
|
|
Down Peers
|
Number of unavailable BGP peers.
|
|
|
Peer
|
Address of each BGP peer.
|
|
|
InPkt
|
Number of packets received from the peer,
|
|
|
OutPkt
|
Number of packets sent to the peer.
|
|
|
Flaps
|
Number of times a BGP session has changed state from Down to Up.
|
A high number of flaps might indicate a problem with the interface on
which the BGP session is enabled.
|
|
Last Up/Down
|
Last time that a session became available or unavailable, since the
neighbor transitioned to or from the established state.
|
If the BGP session is unavailable, this time might be useful in determining
when the problem occurred.
|
|
State
|
A multipurpose field that displays information about BGP peer sessions.
The contents of this field depend upon whether a session is established.
- If a peer is not established, the field shows the state of the
peer session: Active, Connect, or Idle.
- If a BGP session is established, the field shows the number of
active, received, and damped routes that are received from a neighbor. For
example, 2/4/0 indicates two active routes, four received routes,
and no damped routes.
|
|
| BGP Neighbors |
|
|
Peer
|
Address of the BGP neighbor.
|
|
|
AS
|
AS number of the peer.
|
|
|
Type
|
Type of peer: Internal or External.
|
|
|
State
|
Current state of the BGP session:
-
Active—BGP is initiating a TCP connection in an
attempt to connect to a peer. If the connection is successful, BGP sends an
open message.
-
Connect—BGP is waiting for the TCP connection to
become complete.
-
Established—The BGP session has been established,
and the peers are exchanging BGP update messages.
-
Idle—This is the first stage of a connection. BGP
is waiting for a Start event.
-
OpenConfirm—BGP has acknowledged receipt of an
open message from the peer and is waiting to receive a keepalive or notification
message.
-
OpenSent—BGP has sent an open message and is waiting
to receive an open message from the peer.
|
Generally, the most common states are Active, which indicates
a problem establishing the BGP conenction, and Established, which
indicates a successful session setup. The other states are transition states,
and BGP sessions normally do not stay in those states for extended periods
of time.
|
|
Export
|
Names of any export policies configured on the peer.
|
|
|
Import
|
Names of any import policies configured on the peer.
|
|
|
Number of flaps
|
Number of times the BGP sessions has changed state from Down to Up.
|
A high number of flaps might indicate a problem with the interface on
which the session is established.
|
| OSPF Neighbors |
|
|
Address
|
Address of the neighbor.
|
|
|
Interface
|
Interface through which the neighbor is reachable.
|
|
|
State
|
State of the neighbor: Attempt, Down, Exchange, ExStart, Full, Init, Loading,
or 2way.
|
Generally, only the Down state, indicating a failed OSPF adjacency,
and the Full state, indicating a functional adjacency, are maintained
for more than a few seconds. The other states are transitional states that
a neighbor is in only briefly while an OSPF adjacency is being established.
|
|
ID
|
Router ID of the neighbor.
|
|
|
Priority
|

|
Interface
|
Name of the interface running OSPF.
|
|
|
State
|
State of the interface: BDR, Down, DR, DRother, Loop, PtToPt,
or Waiting.
|
The Down state, indicating that the interface is not functioning,
and PtToPt state, indicating that a point-to-point connection has
been established, are the most common states.
|
|
