Displaying BGP4+ information
State The state of the session with the neighbor. The states are from the
perspective of this device of the session, not the perspective of the
neighbor. 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.
•
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: When 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. When the device receives a KEEPALIVE
message from the neighbor, the state changes to Established.
When the message is a NOTIFICATION, the state changes to Idle.
•
ESTABLISHED – BGP4 is ready to exchange UPDATE messages
with the neighbor.
•
When there is more BGP data in the TCP receiver queue, a plus
sign (+) is also displayed.
NOTE: When the user displays information for the neighbor using the
show ip bgp neighbor ip-addr command, the TCP receiver queue
value is greater than 0.
Time The amount of time this session has been in its current state.
KeepAliveTime The KeeAliveTime, which specifies how often this device sends keep
alive messages to the neighbor.
HoldTime The hold time, which specifies how many seconds the device waits for a
KEEPALIVE or UPDATE message from a BGP4 neighbor before deciding
that the neighbor is dead.
Minimal Route Advertisement Interval The minimum time elapse between route advertisements to the same
neighbor.
RefreshCapability Indicates whether this Brocade device has received confirmation from
the neighbor that the neighbor supports the dynamic refresh capability.
SendExtenedCommunity: Capability to send extended community route targets to peer for
filtering.
Messages Sent The number of messages this device has sent to the neighbor. The
display shows statistics for the following message types:
•
Open
•
Update
•
KeepAlive
•
Notification
•
Refresh-Req
