558 CHAPTER 49: BGP/MPLS VPN CONFIGURATION
Configuration procedure
n
This configuration procedure has omitted configurations between PE and P, and
configurations on CEs. For these details refer to the former example.
1 Configure PE-A:
# Configure VPN-instance 1 for VPN1 on PE-A, so that it can send and receive VPN
routing information of VPN-target 111:1.
[PE-A] ip vpn-instance vpn-instance 1
[PE-A-vpn-1] route-distinguisher 100:1
[PE-A-vpn-1] vpn-target 111:1 both
[PE-A-vpn-1] quit
# Set up MP-EBGP adjacency between PE-A and CE-A, import intra-CE-A VPN
routes learned into MBGP VPN-instance address family.
[PE-A] bgp 100
[PE-A-bgp] ipv4-family vpn-instance vpn-instance1
[PE-A-bgp-af-vpn-instance] import-route direct
[PE-A-bgp-af-vpn-instance] import-route static
[PE-A-bgp-af-vpn-instance] group 172 external
[PE-A-bgp-af-vpn-instance] peer 172.15.1.1 group 172 as-number 65011
[PE-A-bgp-af-vpn-instance] quit
[PE-A-bgp] quit
# Bind VPN-instance1 with the interface of VLAN301 which connects CE-A.
[PE-A] vlan 301
[PE-A-vlan301] port gigabitethernet 3/1/1
[PE-A-vlan301] quit
[PE-A] interface Vlan-interface 301
[PE-A-Vlan-interface301] ip binding vpn-instance vpn-instance1
[PE-A-Vlan-interface301] ip address 172.15.0.1 255.255.0.0
[PE-A-Vlan-interface301] quit
# Configure Loopback interface
[PE-A] interface loopback 0
[PE-A-LoopBack0] ip address 10.1.1.1 255.255.255.255
[PE-A-LoopBack0] quit
# Configure MPLS basic capacity.
[PE-A] mpls lsr-id 10.1.1.1
[PE-A] mpls
[PE-A-mpls] quit
[PE-A] mpls ldp
# Set up MP-IBGP adjacency between PEs to exchange inter-PE VPN routing
information and activate MP-IBGP peer in VPNv4 sub-address family view.
[PE-A] bgp 100
[PE-A-bgp] group 20 internal
[PE-A-bgp] peer 20.1.1.1 group 20
