Verifying RSVP Configuration
This figure illustrates the topology.
Figure 10: Sample Topology
Perform the following steps to verify RSVP configuration.
SUMMARY STEPS
1.
show rsvp session
2.
show rsvp counters messages summary
3.
show rsvp counters events
4.
show rsvp interface type interface-path-id [detail]
5.
show rsvp graceful-restart
6.
show rsvp graceful-restart [neighbors ip-address | detail]
7.
show rsvp interface
8.
show rsvp neighbor
DETAILED STEPS
Step 1
show rsvp session
Verifies that all routers on the path of the LSP are configured with at least one Path State Block (PSB) and one Reservation
State Block (RSB) per session.
Example:
RP/0/RP0/CPU0:router# show rsvp session
Type Destination Add DPort Proto/ExtTunID PSBs RSBs Reqs
---- --------------- ----- --------------- ----- ----- ----- LSP4
172.16.70.70 6 10.51.51.51 1 1 0
In the example , the output represents an LSP from ingress (head) router 10.51.51.51 to egress (tail) router 172.16.70.70.
The tunnel ID (also called the destination port) is 6.
Example:
If no states can be found for a session that should be up, verify the
application (for example, MPLS-TE and O-UNI) to see if
everything is in order. If a session has one PSB but no RSB, this indicates
that either the Path message is not making it to the egress (tail) router or
the reservation message is not making it back to the router R1 in question.
