Advertise the Default BGP4 Route to a Specific Neighbor

You can configure a BGP device to advertise the default IPv4 route to a specific neighbor.

Procedure

  1. Access global configuration mode.
    device# configure terminal
  2. Access BGP configuration mode.
    device(config)# router bgp
  3. Specify the autonomous system in which your device resides.
    device(config-bgp-router)# local-as 1000
  4. Access address-family IPv4 unicast configuration mode.
    device(config-bgp-router)# address-family ipv4 unicast
  5. Enable the BGP4 device to advertise the default IPv4 route to a specific neighbor.
    device(config-bgp-ipv4u)# neighbor 10.4.4.4 default-originate
    This example enables the device to advertise the default route to the 10.4.4.4 neighbor.
