PE3(config-bgp)#neighbor 4.5.6.7 update-source loopback1
PE3(config-bgp)#address-family vpnv4
PE3(config-bgp-af-vpnv4)#neighbor 4.5.6.7 active
Configuration of PE4 is the same to PE3.
5. PE2 specifies PE3 as its EBGP neighbor in BGP VPNv4 address family mode. IP
address of INTB is 150.3.2.3.
PE2(config)#router bgp 100
PE2(config-bgp)#address-family ipv4 vrf vpn1
PE2(config-bgp-af-ipv4-vrf)#neighbor 150.3.2.3 remote-as 200
6. Bind vpn1 to PE3.
PE3(config)#interface INTB
PE3(config-if-INTB)#ip vrf forwarding vpn1
PE3(config-if-INTB)#ip address 150.3.2.3 255.255.255.0
7. Bind vpn1 to PE2.
PE2(config)#interface INTA
PE2(config-if-INTA)#ip vrf forwarding vpn1
PE2(config-if-INTA)#ip address 150.3.2.2 255.255.255.0
8. PE3 specifies PE2 as its EBGP neighbor in VPNv4 address family mode. IP address
of INTB is 150.3.2.2.
PE3(config)#router bgp 200
PE3(config-bgp)#address-family ipv4 vrf vpn1
PE3(config-bgp-af-ipv4-vrf)#neighbor 150.3.2.2 remote-as 100
9. PE1 redistributes direct-connected route in VPNv4 address family mode.
PE1(config)#router bgp 100
PE1(config-bgp)#address-family ipv4 vrf vpn1
PE1(config-bgp-ipv4-vrf)#redistribute connected
10. PE4 advertises the network segment 200.1.1.0 in VPNv4 address family mode.
PE4(config)#router bgp 200
PE4(config-bgp)#address-family ipv4 vrf vpn1
PE4(config-bgp-af-ipv4-vrf)#network 200.1.1.0 255.255.255.0
11. Enable LDP between PE1 and PE2 to establish LSP. The interface vlan1 is used to
interconnected PE2 by PE1.
PE1(config)#mpls ldp instance 1
PE1(config-ldp-1)#interface vlan1
PE1(config-ldp-1-vlan1)#exit
PE1(config-ldp-1)#exit
PE1(config)#mpls interface vlan1
Enable LDP between PE3 and PE4 to establish LSP.
Configuration Verification
Use show bgp vpnv4 unicast vrf vpn1 summary on PE1 to view the EBGP neighborhood
establishing with 100.1.1.2.
