protocols bgp <asn> neighbor <id> address-family ipv6-unicast default-originate
Enables or disables forwarding of the default route to a BGP neighbor.
The default route is not distributed.
- asn
- The number for the AS in which this router resides. The number ranges from 1 through 4294967295.
- id
- The IPv4 or IPv6 address of a BGP neighbor.
- map-name
- Specifies a configured route map to be used when advertising the default route.

This command applies to IPv6 unicast routes only.
Use the set form of this command to enable the router to advertise the default route ::/0 to this BGP neighbor. This route can then be used by the neighbor to reach the local router if no other routes are available.
The route ::/0 need not be explicitly configured on the local router.
If a route map is specified, the default route is advertised if two conditions are satisfied:
- The route map includes a match ip address clause.
- A route exists that exactly matches the IP access list.
Route maps are configured using protocols bgp <asn> neighbor <id> local-as <asn>.
Use the delete form of this command to disable forwarding of the default route or to delete a route map.
Use the show form of this command to view BGP neighbor default route origination settings.
