Displaying BGP4 information

RouterID The neighbor router ID.
Description The description you gave the neighbor when you configured it on the Layer 3
Switch.
State The state of the router session with the neighbor. The states are from this router
perspective of the session, not the neighbor perspective. The state values are
based on the BGP4 state machine values described in RFC 1771 and can be one
of the following for each router:
IDLE – The BGP4 process is waiting to be started. Usually, enabling BGP4 or
establishing a neighbor session starts the BGP4 process.
A minus sign (-) indicates that the session has gone down and the software is
clearing or removing routes.
ADMND – The neighbor has been administratively shut down. Refer to
“Administratively shutting down a session with a BGP4 neighbor” on
page 1003.
A minus sign (-) indicates that the session has gone down and the software is
clearing or removing routes.
CONNECT – BGP4 is waiting for the connection process for the TCP neighbor
session to be completed.
ACTIVE – BGP4 is waiting for a TCP connection from the neighbor.
NOTE: If the state frequently changes between CONNECT and ACTIVE, there may
be a problem with the TCP connection.
OPEN SENT – BGP4 is waiting for an Open message from the neighbor.
OPEN CONFIRM – BGP4 has received an OPEN message from the neighbor
and is now waiting for either a KEEPALIVE or NOTIFICATION message. If the
router receives a KEEPALIVE message from the neighbor, the state changes
to Established. If the message is a NOTIFICATION, the state changes to Idle.
ESTABLISHED – BGP4 is ready to exchange UPDATE messages with the
neighbor.
If there is more BGP data in the TCP receiver queue, a plus sign (+) is also
displayed.
NOTE: If you display information for the neighbor using the show ip bgp neighbors
<ip-addr> command, the TCP receiver queue value will be greater than 0.
Time The amount of time this session has been in its current state.
KeepAliveTime The keep alive time, which specifies how often this router sends keep alive
messages to the neighbor. Refer to “Changing the Keep Alive Time and Hold Time”
on page 1004.
HoldTime The hold time, which specifies how many seconds the router will wait for a
KEEPALIVE or UPDATE message from a BGP4 neighbor before deciding that the
neighbor is dead. Refer to “Changing the Keep Alive Time and Hold Time” on
page 1004.
PeerGroup The name of the peer group the neighbor is in, if applicable.
Multihop-EBGP Whether this option is enabled for the neighbor.
RouteReflectorClient Whether this option is enabled for the neighbor.
SendCommunity Whether this option is enabled for the neighbor.
NextHopSelf Whether this option is enabled for the neighbor.
DefaultOriginate Whether this option is enabled for the neighbor.
MaximumPrefixLimit Lists the maximum number of prefixes the Layer 3 Switch will accept from this
neighbor.
