Usage
Information
To view the total number of COMMUNITY attributes found, use the show ip bgp
summary command. The text line above the route table states the number of
COMMUNITY attributes found.
The show ip bgp community command without any parameters lists BGP
routes with at least one BGP community attribute and the output is the same as for
the
show ip bgp command output.
IPv6 BGP Commands
IPv6 Border Gateway Protocol (IPv6 BGP) is supported on the MXL 10/40GbE Switch IO Module.
Border gateway protocol (BGP) is an external gateway protocol that transmits interdomain routing
information within and between autonomous systems (AS). BGP version 4 (BGPv4) supports classless
interdomain routing and the aggregation of routes and AS paths. Basically, two routers (called neighbors
or peers) exchange information including full routing tables and periodically send messages to update
those routing tables.
bgp soft-reconfig-backup
To avoid the peer from resending messages, use this command only when route-refresh is not
negotiated.
Syntax

ip bgp soft in
command, the update database stored in the router is replayed
and updates are re-evaluated. With this command, the replay and update process is
triggered only if route-refresh request is not negotiated with the peer. If the
request is indeed negotiated (after executing the clear ip bgp soft in
