Configuring BGP VPNv6 route control

BGP VPNv6 route control is configured similarly with BGP route control, except that it is configured in

family view.
4. Configure filtering of
advertised routes.
5. Configure filtering of
received routes.
6. Advertise the COMMUNITY
attribute to a peer or peer
group.
7. Allow the local AS number to
appear in the AS_PATH
attribute of routes received
from the peer, and set the
maximum number of
repetitions.
8. Filter routes received from or
advertised to a peer or peer
group based on an AS_PATH
list.
9. Configure ACL-based route
filtering for the specified peer
or peer group.
10. Configure IPv6 prefix
list-based route filtering for
the specified peer or peer
group.
11. Specify a preferred value for
routes received from the
peer or peer group.

to the peer to carry only
public AS numbers.

routes advertised to or
received from the peer or
peer group.
