Configuring EBGP on a CE router

Allows route exchanges between a CE router and its associated PE router by enabling BGP on a customer edge (CE) router and configuring an associated premises edge (PE) router as a BGP neighbor.

The following task shows the steps required for enabling BGP on a CE device and assigning a PE device as a BGP neighbor. For an example of a full configuration required to exchange routes in an external BGP (EBGP) network, see the EBGP for route exchange task.
  1. On a CE device, enter the configure terminal command.
    device# configure terminal
  2. Enter the router bgp command to enable BGP routing.
    device(config)# router bgp
  3. Enter the local-as command to configure the AS number.
    device(config-bgp)# local-as 2
  4. Configure a PE BGP neighbor using the neighbor remote-as command.
    device(config-bgp)# neighbor 10.33.33.3 remote-as 1

Example

The following example enables BGP on a CE and assigns a PE as a BGP neighbor.

device# configure terminal
device(config)# router bgp 
device(config-bgp)# local-as 2
device(config-bgp)# neighbor 10.33.33.3 remote-as 1
