ZXAN(config-if-vlan11)#exit
5. Configure the routing protocol.
ZXAN(config)#router ospf 1
ZXAN(config-router)#network 3.3.3.3 0.0.0.0 area 0.0.0.0
ZXAN(config-router)#network 11.1.1.0 0.0.0.255 area 0.0.0.0
6. Configure the GR function.
ZXAN(config-router)#nsf
ZXAN(config-router)#grace-period 180
ZXAN(config-router)#exit
7. Enable the global MPLS function.
ZXAN(config)#mpls ldp router-id loopback1
ZXAN(config)#mpls ldp graceful-restart
ZXAN(config)#mpls ip
8. Save the configuration data.
Result
The LDP GR function is successfully configured. Execute the command ping mpls ipv
4 3.3.3.3 on C300-1. The ping is successful. When you swap the active and backup
control switching cards on C300-2, the LDP session between C300-1 and C300-3 is not
interrupted.
