Use to negotiate the exchange of inbound route filters and their installation as
ORFs by specifying the orf keyword, an ORF type, and the direction of the
capability.
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.
You cannot configure the receive direction for the orf capability for a peer that
is a member of a peer group or for a peer.
When issued with the orf keyword, this command takes effect immediately and
automatically bounces the BGP session.
Example
host1(config-router)#neighbor 192.168.1.158 capability orf prefix-list both
Use the no version to prevent advertisement of the capability. Use the default
version to restore the default, advertising the capability.
See neighbor capability.
Use to set the maximum number of ORF entries of any one type that will be
accepted from the specified neighbor.
Example
host1(config-router)#neighbor 192.168.1.158 maximum-orf-entries 125000
Use the no version to restore the default value of no limits.
See neighbor maximum-orf-entries.
Use to assign an inbound or outbound prefix list.
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. However, you cannot
configure a member of a peer group to override the inherited peer group
characteristic for outbound policy.
Example
host1(config-router)#neighbor 192.168.1.158 prefix-list seoul19 in
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
