BGP Extended Communities (RFC 4360)
BGP Extended Communities, as defined in RFC 4360, is an optional transitive BGP attribute. It
provides two major advantages over Standard Communities:
• The range is extended from 4-octet (AA:NN) to 8-octet (Type:Value) to provide enough number
communities.
• Communities are structured using a new “Type” field (1 or 2-octets), allowing you to provide
granular control/filter routing information based on the type of extended communities.
The BGP Extended Community commands are:
• deny
• deny regex
• description
• ip extcommunity-list
• match extcommunity
• permit
• permit regex
• set extcommunity rt
• set extcommunity soo
• show ip bgp ipv4 extcommunity-list
• show ip bgp paths extcommunity
• show ip extcommunity-list
InQ Displays the number of messages from that neighbor waiting to be processed.
OutQ Displays the number of messages waiting to be sent to that neighbor.
If a number appears in parentheses, the number represents the number of messages
waiting to be sent to the peer group.
Up/Down Displays the amount of time (in hours:minutes:seconds) that the neighbor is in the
Established stage.
If the neighbor has never moved into the Established stage, the word never is
displayed.
State/Pfx If the neighbor is in Established stage, the number of network prefixes received.
If a maximum limit was configured with the neighbor maximum-prefix command,
(prfxd) appears in this column.
If the neighbor is not in Established stage, the current stage is displayed (Idle,
Connect, Active, OpenSent, OpenConfirm) When the peer is transitioning between
states and clearing the routes received, the phrase (Purging) may appear in this
column.
If the neighbor is disabled, the phrase (Admin shut) appears in this column.
