DES-7200 Configuration Guide Chapter 3 MPLS Reliability Configuration
3-11
## Configurations on the router. You need to execute one more command: enable fast
forwarding.
DES-7200(config-if-GigabitEthernet 2/2)#mpls ip
DES-7200(config-if-GigabitEthernet 2/2)#ip ref
Router(config-if-GigabitEthernet 2/2)#exit
3) Configure LDP protocol so that the network can forward MPLS traffic.
# Configure PE1.
DES-7200#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
DES-7200(config)#mpls router ldp
DES-7200(config-mpls-router)#ldp router-id interface loopback 0 force
# Configure P device.
DES-7200#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
DES-7200(config)#mpls router ldp
DES-7200(config-mpls-router)#ldp router-id interface loopback 0 force
4) Enable LDP GR protocol
# Configure PE1.
DES-7200#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
DES-7200(config)#mpls router ldp
DES-7200(config-mpls-router)#graceful-restart
# Configure P device.
DES-7200#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
DES-7200(config)#mpls router ldp
DES-7200(config-mpls-router)#graceful-restart
5) Configure relevant parameters of LDP GR protocol.
# Configure PE1.
DES-7200#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
DES-7200(config)#mpls router ldp
## Set reconnection timer to 300 seconds, LDP neighbor liveness timer to 120 seconds and LDP
recovery timer to 120 seconds.
