To view graceful restart information for IS-IS and OSPF, configure traceoptions (see
"Tracking Graceful Restart Events" on page
Here is the output of a traceoptions log from an OSPF restarting router:
Oct 8 05:20:12 Restart mode - sending grace lsas
Oct 8 05:20:12 Restart mode - estimated restart duration timer triggered
Oct 8 05:20:13 Restart mode - Sending more grace lsas
Here is the output of a traceoptions log from an OSPF helper router:
Oct 8 05:20:14 Helper mode for neighbor 192.0.2.5
Oct 8 05:20:14 Received multiple grace lsa from 192.0.2.5
To view graceful restart information for CCC and TCC connections, use the
connections command. The following example assumes four remote interface CCC
connections between CE1 and CE2:
user@PE1> show connections
CCC and TCC connections [Link Monitoring On]
