overridden for a specific peer. However, you cannot configure a member of a peer group
to override the inherited peer group characteristic for outbound policy.
•
New policy values are applied to all routes that are sent (outbound policy) or received
(inbound policy) after you issue the command.
To apply the new policy to routes that are already present in the BGP routing table,
you must use the
clear ip bgp command to perform a soft clear or hard clear of the
current BGP session.
Behavior is different for outbound policies configured for peer groups for which you
have enabled Adj-RIBs-Out. If you change the outbound policy for such a peer group
and want to fill the Adj-RIBs-Out table for that peer group with the results of the new
policy, you must use the
clear ip bgp peer-group command to perform a hard clear or
outbound soft clear of the peer group. You cannot merely perform a hard clear or
outbound soft clear for individual peer group members because that causes BGP to
resend only the contents of the Adj-RIBs-Out table.

Use the no version to remove the filter list.

See neighbor filter-list.
neighbor weight
•
Use to assign a weight to a neighbor connection.
•
All routes learned from this neighbor will have the assigned weight initially.
•
The route with the highest weight will be chosen as the preferred route when multiple
routes are available to a particular network.
•
The weights assigned with the set weight commands in a route map override the
weights assigned with the neighbor weight and neighbor filter-list commands.
•
If you specify a BGP peer group by using the peerGroupName argument, all the members
of the peer group inherit the characteristic configured with this command unless it is
overridden for a specific peer.
