Not advertised by default.
With the peer default-route-advertise

default route with the next hop as itself
to the specified IPv6 MBGP peer or the
specified peer group, regardless of
whether the default route is available in
the routing table.

Configure outbound IPv6
MBGP route filtering.
•
Configure the filtering of outgoing
routes:
filter-policy { acl6-number |
ipv6-prefix ipv6-prefix-name } export
[ protocol process-id ]
•
Specify an IPv6 ACL to filter routes
advertised to a peer or a peer group:
peer { ipv6-group-name |
ipv6-address } filter-policy
acl6-number export
•
Specify an AS path list to filter IPv6
MBGP routing information advertised
to a peer or a peer group:
peer { ipv6-group-name |
ipv6-address } as-path-acl
as-path-acl-number export
•
Specify an IPv6 prefix list to filter
routes advertised to a peer or a peer
group:
peer { ipv6-group-name |
ipv6-address } ipv6-prefix
ipv6-prefix-name export
•
Apply a routing policy to routes
advertised to a peer or a peer group:
peer { ipv6-group-name |
ipv6-address } route-policy
route-policy-name export
Use any of the methods.
By default, no filtering is
configured.
You can configure filter
policies as required. If you
configure multiple filter
policies, they are applied in
the following order:
5.
filter-policy export.
6.
peer filter-policy export.
7.
peer as-path-acl export.
8.
peer ipv6-prefix export.
9.
peer route-policy
export.
A filter policy can be applied
only after the previous one is
passed. Routing information
can be advertised only after
passing all the configured
filter policies.
