Examples

The following example sends the IPv4 default route to the BGP4 neighbor 10.11.12.13.

device# configure terminal 
device(config)# router bgp
device(config-bgp-router)# address-family ipv4 unicast
device(config-bgp-ipv4u)# neighbor 10.11.12.13 default-originate

The following example sends IPv6 default route to the BGP4 neighbor 10.11.12.13.

device# configure terminal
device(config)# router bgp
device(config-bgp-router)# address-family ipv6 unicast
device(config-bgp-ipv6u)# neighbor 10.11.12.13 default-originate
