Allied Telesis VERSION 5.4.3-2.6 manual Neighbor capability orf prefix-list BGP and BGP4+

BGP and BGP4+ Commands

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 {bothreceivesend}

no neighbor <neighborid> capability orf prefix-list {bothreceive send}

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.

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.
