Step 5 Configure VPN instances on each PE and connect the CEs to the PEs.
# Configure PE1.
[PE1] ip vpn-instance vpn1
[PE1-vpn-instance-vpn1] route-distinguisher 100:1
[PE1-vpn-instance-vpn1] vpn-target 111:1
[PE1-vpn-instance-vpn1] quit
# Configure PE2.
[PE2] ip vpn-instance vpn1
[PE2-vpn-instance-vpn1] route-distinguisher 100:2
[PE2-vpn-instance-vpn1] vpn-target 111:1
[PE2-vpn-instance-vpn1] quit
[PE2] interface vlanif 20
[PE2-Vlanif20] ip binding vpn-instance vpn1
[PE2-Vlanif20] ip address 10.1.1.2 30
[PE2-Vlanif20] quit
# Configure PE3.
[PE3] ip vpn-instance vpn1
[PE3-vpn-instance-vpn1] route-distinguisher 100:3
[PE3-vpn-instance-vpn1] vpn-target 111:1
[PE3-vpn-instance-vpn1] quit
[PE3] interface vlanif 40
[PE3-Vlanif40] ip binding vpn-instance vpn1
[PE3-Vlanif40] ip address 10.2.1.2 30
