Configuration tips
Configuration tips for PE1, P and PE2 are shown below:
1) Configure VRF.
2) Configure IP address and OSPF protocol on the interface of respective devices.
3) Configure global and interface MPLS capability on respective devices.
4) Configure LDP protocol so that the network can forward MPLS traffic.
5) Enable LDP GR protocol and configure relevant parameters of LDP GR protocol.
6) Configure L3VPN.
7) Enable BGP GR protocol.
8) Restart LDP session to effect the configurations.
Configuration steps
1) Configure VRF.
# Configure PE1.
DES-7200#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
## Configure VRF.
DES-7200(config)#ip vrf 10
DES-7200(config-vrf)#rd 1:100
DES-7200(config-vrf)#route-target both 1:100
DES-7200(config-vrf)#exit
# Configure P. VRF configuration is not required.
# Configure PE2. The configurations of PE2 are the same as that of PE1.
2) Configure IP address and OSPF protocol on the interface of respective devices.
# Configure PE1.
DES-7200#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
## Configure the IP address of interface (Gi 2/1) and associate VRF with the interface.
DES-7200(config)#interface gigabitEthernet 2/1
