Configuring MPLS Quick Steps for Configuring MPLS
OmniSwitch AOS Release 6 Network Configuration Guide September 2009 page 10-7
5 Configure keepalive timeout interval for targeted LDP sessions using the configure router ldp
targeted-session keepalive command. For example:
-> configure router ldp targeted-session keepalive 40 2
Quick Steps for Configuring LDP Graceful Restart
The graceful restart mechanism is always enabled for the switch. The following steps provide a quick tuto-
rial for configuring the graceful restart helper status and timers:
1 Enable the Graceful Restart Helper for the switch using the configure router ldp graceful-restart-
helper command. For example:
-> configure router ldp graceful-restart-helper
2 Configure the reconnect time advertised to neighboring LDP routers using the configure router ldp
reconnect-time command. For example:
-> configure router ldp reconnect-time 300
3 Configure the MPLS forwarding state hold time using the configure router ldp fwd-state-holding-
time command. For example:
-> configure router ldp fwd-state-holding-time 300
4 Configure the amount of time stale label-FEC bindings are retained using the configure router ldp
maximum-recovery-time command. For example:
-> configure router ldp maximum-recovery-time 300
5 Configure the amount of time to wait for a neighbor to re-establish an LDP session using the configure
router ldp neighbor-liveness-time command. For example:
-> configure router ldp neighbor-liveness-time 300
Note. Optional. Verify LDP parameter settings using the show router ldp parameters command. For
example:
->show router ldp parameters
