## Configurations on the router. You need to execute one more command: enable fast
forwarding.
DES-7200(config-if-GigabitEthernet 0/1)#mpls ip
DES-7200(config-if-GigabitEthernet 0/1)#ip ref
Router(config-if-GigabitEthernet 0/1)#exit
DES-7200(config)#interface gigabitEthernet 0/2
DES-7200(config-if-GigabitEthernet 0/2)#label-switching
## Configurations on the switch.
DES-7200(config-if-GigabitEthernet 0/2)#mpls ip
Router(config-if-GigabitEthernet 0/2)#exit
## Configurations on the router. You need to execute one more command: enable fast

DES-7200(config-if-GigabitEthernet 0/2)#mpls ip
DES-7200(config-if-GigabitEthernet 0/2)#ip ref
Router(config-if-GigabitEthernet 0/2)#exit
# The configurations of other nodes are the same as that of PE1.
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 P1
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
# The configurations of other nodes are the same as that of PE1.
4) Configure BFD for LDP LSP1 on PE1.
DES-7200#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
DES-7200(config)#interface gigabitEthernet 0/2
DES-7200(config-if-GigabitEthernet 0/2)#no bfd echo
