bgp orf extcomm-filter

This command specifies whether the Outbound Route Filtering (ORF) capability for extended community filtering is to be sent to the BGP peer, received from the BGP peer, or both.

Syntax

bgp orf {ipv4 | ipv6} {unicast | multicast} extcomm-filter {send | receive | both}
no orf {ipv4 | ipv6} {unicast | multicast} extcomm-filter {send | receive | both}

Parameters

ipv4 | ipv6 unicast Specifies the ORF configuration applies to IPv4 unicast or IPv6 addresses.
send Specifies that the ORF capability for extended community filtering is sent to the BGP peer.
receive Specifies that the ORF capability for extended community filtering is received from the BGP peer.
both Specifies that the ORF capability for extended community filtering is both sent to and received from the BGP peer.

Defaults

None.

Mode

BGP Router Configuration.

Usage

This command is used to reduce the number of BGP extended community filtering advertisements the BGP speaker sends or receives from a peer router.

Most configurations will configure BGP to advertise both send and receive ORF extended community filtering capabilities. This feature can be configured in a single direction between two routers with one router configured to send and the other router configured to receive the ORF extended community filtering capability.

The bgp orf extcomm-filter command specifies whether the ORF capability for extended community filtering is to be sent to a BGP peer, received from a BGP peer, or both.

The no bgp orf extcomm-filter command removes the configured ORF capability.

Example

This example specifies BGP to send the ORF capability for extended community filtering for IPv4 unicast to the peer:

System(su-config)->router bgp 65151
System(su-config-bgp)->bgp router-id 151.1.1.9
System(su-config-bgp)->bgp orf ipv4 unicast extcomm-filter send
System(su-config-bgp)->
