■
Use the no version to delete an IPv6 access list (no other options specified), the
specified entry in the access list, or the log for the specified access list or entry
(by specifying the
log keyword).
■
See ipv6 access-list.
neighbor distribute-list
■
Use to filter routes to selected prefixes as specified in an access list. Distribute
lists are applied only to external peers.
■
Use the in keyword to apply the list to inbound routes (inbound policy). Use the
out keyword to apply the list to outbound routes (outbound policy).
■
Besides using distribute lists to filter BGP advertisements, you can do the
following:
■
Use AS-path filters with the ip as-path access-list and the neighbor filter-list
commands
■
Use route map filters with the route-map and the neighbor route-map
commands
■
Example
host1:vr1(config-router)# neighbor group1 distribute-list list1 in
■
Use the no version to disassociate the access list from a neighbor.
■
See neighbor distribute-list.
neighbor filter-list
■
Use to assign an AS-path access list to matching inbound or outbound routes.
■
Use the in keyword to apply the list to inbound routes (inbound policy). Use the
out keyword to apply the list to outbound routes (outbound policy).
■
You can specify an optional weight value with the weight keyword to assign a
relative importance to incoming routes that match the AS-path access list.
■
Access list values can be in the range 0–65535.
■
Example
host1:vr1(config-router)# neighbor group2 filter-list list2 out
■
Use the no version to disassociate the access list from a neighbor.
■
See neighbor filter-list.
neighbor prefix-list
■
Use to assign an inbound or outbound prefix list.
■
If you specify a BGP peer group by using the peer-group-name argument, all the
members of the peer group inherit the characteristic configured with this
command unless it is overridden for a specific peer.
