Advertising the default BGP4+ route to a specific neighbor

A BGP device can be configured to advertise the default IPv6 route to a specific neighbor.

About this task

Procedure

  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 address-family ipv6 unicast command to enter IPv6 address family configuration mode.
    device(config-bgp-router)# address-family ipv6 unicast
  5. Enter the neighbor default-originate command and specify an IPv6 address to enable the BGP4+ device to advertise the default IPv6 route to a specific neighbor.
    device(config-bgp-ipv6u)# neighbor 2001:db8:93e8:cc00::1 default-originate

Example

The following example enables a BGP4+ device to advertise the default IPv6 route to a specific neighbor.

device# configure terminal
device(config)# router bgp
device(config-bgp-router)# local-as 1000
device(config-bgp-router)# address-family ipv6 unicast
device(config-bgp-ipv6u)# neighbor 2001:db8:93e8:cc00::1 default-originate
