neighbor capability orf prefix-list (BGP and BGP4+)
Use this command to advertise ORF (Outbound Route Filters) capability to neighbors. Use
this command to dynamically filter updates. The BGP speaker can advertise a prefix list
with prefixes it wishes the peer to prune or filter from outgoing updates.
Use the no variant of this command to disable this function.
Syntax [BGP/BGP4+] neighbor <neighborid> capability orf prefix-list {both|receive|send}
no neighbor <neighborid> capability orf prefix-list {both|receive|
send}
Mode [BGP]
Router Configuration or IPv4 Address Family Configuration for a VRF instance
Mode [BGP4+] IPv6 Address Family Configuration
Default [BGP/BGP4+] Disabled
Usage [BGP/BGP4+] Outbound Route Filters (ORFs) send and receive capabilities to lessen the number of
updates exchanged between neighbors. By filtering updates, this option minimizes
generating and processing of updates. The local router advertises the ORF capability in
send mode and the remote router receives the ORF capability in receive mode applying
the filter as outbound policy. The two routers exchange updates to maintain the ORF for
each router. Only an individual router or a peer-group can be configured to be in receive
or send mode. A peer-group member cannot be configured in receive or send mode.
Parameter Description
<neighborid>{<ip-address>|<ipv6-addr>|<peer-group>}
<ip-address>
Specify the address of an IPv4 BGP neighbor,
in dotted decimal notation A.B.C.D.
<ipv6-addr> Specify the address of an IPv6 BGP4+
neighbor, entered in hexadecimal in the
format X:X::X:X.
<peer-group> Enter the name of an existing peer-group. For
information on how to create peer groups,
refer to the neighbor peer-group (add a
neighbor) (BGP and BGP+) command on
page 3.144, and neighbor route-map (BGP
and BGP4+) command on page 3.159. When
this parameter is used with this command, the
command applies on all peers in the specified
group.
orf Advertises ORF capability to its neighbors.
both Indicates that the local router can send ORF entries to its peer as well
as receive ORF entries from its peer.
receive Indicates that the local router is willing to receive ORF entries from
its peer.
send Indicates that the local router is willing to send ORF entries to its
peer.
