BGP/MPLS VPN Configuration BGP/MPLS VPN Configuration Example

BGP/MPLS VPN configuration--PE(1)

1. Create VRF and configure related parameter；

2. Add interface to VRF；

PE(config)# ip vrf vrf-namePE(config-vrf)# rd route-distinguisher PE(config-vrf)# route-target import extended-community PE(config-vrf)# route-target export extended-community

PE(config-if)# ip vrf forwarding vrf-name

BGP/MPLS VPN basic configuration--PE(2)

3. Define VRF route between PE and CE

For different dynamic routing protocols, configurations are different on PE, the current version support RIP,OSPF,IS-IS，BGP and static route.


CE and PE run RIPUnder address-family ipv4 vrf mode of RIP, use network command to define interface connected with CE and redistribute BGP to RIP.

PE(config)# router ripPE(config-router)# address-family ipv4 vrf vrf-namePE(config-router-af)# network x.x.x.x m.m.m.mPE(config-router-af)# redistribute connectedPE(config-router-af)# redistribute bgp-int


CE and PE run OSPFStart OSPF VPN process by router ospf command；Define interface connected to CE under this process by using network command, and redistribute BGP to OSPF

PE(config)# router ospf process-id vrf vrf-namePE(config-router)# network x.x.x.x m.m.m.m area xPE(config-router)# redistribute bgp_int


CE and PE run IS-IS protocolstart IS-IS VPN process on PE by command router isis,redistributeBGP under this process

PE(config)# router isis vrf vrf-namePE(config-router)# system-id x.x.xPE(config-router)# area yyPE(config-router)# redistribute protocol bgp level-2


CE and PE run BGPFor BGP ,only need to define CE counterpart under address-family ipv4 vrf address mode of BGP

PE(config)# router bgp as-number PE(config-router)# address-family ipv4 vrf test1PE(config-router-af)# neighbor x.x.x.x remote-as xPE(config-router-af)# exit-address-family


CE and PE run static routeIt is required to configure vpn route for defined vrf to run static route.

PE(config)# ip route vrf vrf-name x.x.x.x m.m.m.m next-hop


4. configure MPBGPConfigure PE counterpart under BGP route configuration mode

PE(config-router)# neighbor x.x.x.x remote-as

Activate PE counterpart under BGP address configuration mode

For different VRF, redistribute the route to MBGP

PE(config-router)# address-family vpnv4PE(config-router-af)# neighbor x.x.x.x activate

PE(config-router)# address-family ipv4 vrf vrf-namePE(config-router-af)# redistribute connected
