Displaying BGP4 information
8
Description The description you gave the neighbor when you configured it on the device.
Local AS The value (if any) of the Local AS configured.
State The state of the session with the neighbor. The states are from the device
perspective, 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 device:
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 234.
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 device 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 BGP4 data in the TCP receiver queue, a plus sign (+) is
also displayed.
NOTE: If you display information for the neighbor using the show ip /jointfilesconvert/1441199/bgp
neighbor ip-addr command, the TCP receiver queue value will be
greater than 0.
Time The amount of time this session has been in the current state.
KeepAliveTime The keep alive time, which specifies how often this device sends keepalive
messages to the neighbor. Refer to “Changing the Keep Alive Time and Hold
Time” on page 243.
HoldTime The hold time, which specifies how many seconds the device will wait for a
keepalive or update message from a BGP4 neighbor before deciding that
the neighbor is not operational. Refer to “Changing the Keep Alive Time and
Hold Time” on page 243.
Multihop-EBGP 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 Maximum number of prefixes the device will accept from this neighbor.
RemovePrivateAs Whether this option is enabled for the neighbor.
