Figure 1-9 MPLS VPN Cross-Domain Configuration Example

Configuration Thought
1. All of PE1, PE2 and PE3, PE4 have VPN1. The RD is 1:1, and the RT is 1:1.
2. Establish LDP, IGP and MPIGP neighborhoods between PE1 and PE2. Establish LDP,
IGP and MP-IBGP neighborhoods between PE3 and PE4. Advertise the loopback
addresses by IGP.
Configuration Commands
1. Bind vpn1 to PE1. Establish EBGP connection between PE1 and CE1.
PE1(config)#router bgp 100
PE1(config-bgp)#address-family ipv4 vrf vpn1
PE1(config-bgp-af-ipv4-vrf)#neighbor 100.1.1.2 remote-as 65000
2. Establish MP-IBGP neighborhood between PE1 and PE2 by using the loopback
interfaces 1.2.3.4 and 2.3.4.5.
PE2(config)#router bgp 100
PE2(config-bgp)#neighbor 1.2.3.4 remote-as 100
PE2(config-bgp)#neighbor 1.2.3.4 update-source loopback1
PE2(config-bgp)#address-family vpnv4
PE2(config-bgp-af-vpnv4)#neighbor 1.2.3.4 active
Configuration of PE1 is the same to PE2.
3. Bind vpn1 to PE4. Establish EBGP connection between PE4 and PE2.
PE4(config)#router bgp 200
PE4(config-bgp)#address-family ipv4 vrf vpn1
PE4(config-bgp-af-ipv4-vrf)#neighbor 200.1.1.2 remote-as 65000
IPv4 and VPNv4 are enabled among PEs.
4. Establish MP-IBGP neighborhood between PE3 and PE4 by using the loopback1
interfaces 3.4.5.6 and 4.5.6.7.
PE3(config)#router bgp 200
PE3(config-bgp)#neighbor 4.5.6.7 remote-as 200
