Check Your Work

To verify proper operation of graceful restart, use the following commands:

• show bgp neighbor (for BGP graceful restart)
• traceoptions (for OSPF graceful restart)
• show rsvp neighbor detail (for RSVP graceful restart—helper router)
• show rsvp version (for RSVP graceful restart—restarting router)
• show ldp session detail (for LDP graceful restart)
• show connections (for CCC and TCC graceful restart)
• show route instance detail (for Layer 3 VPN graceful restart and for any protocols using graceful restart in a routing instance)
• show route protocol l2vpn (for Layer 2 VPN graceful restart)

The following sections show the output of some of these commands as used with the configuration example:

• Router PE1 Status Prior to a Restart
• Router PE1 Status During a Restart

The remaining sections display output of some of these commands generated from other examples:

• Verify OSPF Graceful Restart
• Verify BGP Graceful Restart
• Verify CCC and TCC Graceful Restart
