Advertising the default BGP4+ route

A BGP device can be configured to advertise the default IPv6 route to all BGP4+ neighbors and to install that route in the local BGP4+ route table.
The default route must be present in the local IPv6 route table.
  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 address-family ipv6 unicast command to enter IPv6 address family unicast configuration mode. 
    device(config-bgp-router)# address-family ipv6 unicast
  4. Enter the default-information-originate command to advertise the default IPv6 route to all BGP4+ neighbors and to install that route in the local BGP4+ route table. 
    device(config-bgp-ipv6u)# default-information-originate

The following example enables a BGP4+ device to advertise the default IPv6 route to all BGP4+ neighbors and to install that route in the local BGP4+ route table. 

device# configure terminal
device(config)# router bgp
device(config-bgp-router)# address-family ipv6 unicast
device(config-bgp-ipv6u)# default-information-originate
