Advertising the default BGP4 route to a specific neighbor

A BGP device can be configured to advertise the default IPv4 route to a specific neighbor.
  1. Enter the configure terminal command to access global configuration mode. 
    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 autonomous system number (ASN) in which your device resides. 
    device(config-bgp-router)# local-as 1000
  4. Enter the neighbor default-originate command and specify an IP address to enable the BGP4 device to advertise the default IPv4 route to a specific neighbor. 
    device(config-bgp-router)# neighbor 10.4.4.4 default-originate

The following example enables a BGP4 device to advertise the default IPv4 route to a specific neighbor. 

device# configure terminal
device(config)# router bgp
device(config-bgp-router)# local-as 1000
device(config-bgp-router)# neighbor 10.4.4.4 default-originate
