Allows route exchange between a VRF on a PE router and its associated customer edge (CE) router by enabling BGP on the appropriate VRF of the premises edge (PE) router and configuring the associated CE router as a BGP neighbor.
In this task, a CE is assigned as a BGP neighbor to the VRF VPN1 on a PE device. For an example of a full configuration required to exchange routes in an external BGP (EBGP) network, see the EBGP for route exchange task.
-
On a PE device, enter the
configure terminal command.
device# configure terminal
-
Enter the
router bgp command to enable BGP routing.
device(config)# router bgp
-
Enter the
address-family ipv4 unicast command to assign a VRF.
device(config-bgp)# address-family ipv4 unicast vrf VPN1
-
Enter the
neighbor remote-as command to configure a BGP neighbor (a CE device) to the VRF.
device(config-bgp-ipv4u-vrf)# neighbor 10.33.33.2 remote-as 2
Example
The following example assigns a CE device as a BGP neighbor to the VRF VPN1 on a PE device.
device# configure terminal
device(config)# router bgp
device(config-bgp)# address-family ipv4 unicast vrf VPN1
device(config-bgp-ipv4u-vrf)# neighbor 10.33.33.2 remote-as 2
