The configuration of CE1 is as follows: (the configurations of CE2~CE4 are similar)
CE1#config
CE1(config)# interface vlan 1
CE1(config-if-Vlan1)#ip address 10.1.1.1 255.255.255.0
CE1(config-if-Vlan1)#exit
CE1(config)# interface loopback 1
CE1(config-if-Vlan1)#ip address 192.168.1.1 255.255.255.0
CE1(config-if-Vlan1)# exit
CE1(config)# ip route vrf vpna 192.168.2.1/24 10.1.1.2
The confiugraiton of MPLS BGP on switch PE1 is as follows: (the configuration of PE2 is similar)
(1) Configure VPN instances
PE1#config
PE1(config)#ip vrf vpna
PE1(config-vrf)#rd 100:1
PE1(config-vrf)#route-target both 100:1
PE1(config)#ip vrf vpnb
PE1(config-vrf)#rd 100:2
PE1(config-vrf)#route-target both 100:2
(2) Configure to bind the interface with the VPN instances
PE1(config)# interface vlan 1
PE1(config-if-Vlan1)# ip vrf forwarding vpna
PE1(config-if-Vlan1)#ip address 10.1.1.2 255.255.255.0
PE1(config-if-Vlan1)#exit
PE1(config)# interface vlan 2
PE1(config-if-Vlan2)# ip vrf forwarding vpnb
PE1(config-if-Vlan1)#ip address 10.2.1.2 255.255.255.0
PE1(config-if-Vlan1)#exit
(3) Globally enable MPLS and LDP
PE1(config)#mpls enable
PE1(config)#router ldp
PE1(config-router)#exit
(4) Configure the interface and enable LDP
PE1(config)# interface loopback 1
PE1(config-if-Loopback1)# ip address 172.1.1.1 255.255.255.255
PE1(config-if-Loopback1)# exit
PE1(config)# interface vlan 100
