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.
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. |
None.
BGP Router Configuration.
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.
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)->
