Configure basic BGP/MPLS VPN for First Carrier
# Configure MPLS network: Here we will take PE1 as the example. The configurations of P1 and
PE2 are the same.
## Configure Loopback interface
DES-7200(config)# interface Loopback 0
DES-7200(config-if)# ip address 1.1.1.1 255.255.255.255
DES-7200(config-if)# exit
## Globally enable MPLS and LDP
DES-7200(config)# mpls ip
DES-7200(config)# mpls router ldp
DES-7200(config-mpls-router)# ldp rouer-id interface Loopback 0
DES-7200(config-mpls-router)# exit
## Enable MPLS and LDP on the interface
DES-7200(config)# interface gigabitEthernet 0/0
# In case of a switch, configure the interface to RoutedPort interface (not applicable to a
router)
DES-7200(config-if)# no switchport
# In case of a router, enable fast forwarding on the interface (not applicable to a switch)
DES-7200(config-if)# ip ref
DES-7200(config-if)# ip address 192.168.1.1 255.255.255.0
DES-7200(config-if)# label-switching
DES-7200(config-if)# mpls ip
