State The state of the Brocade device’s session with the neighbor. The states are from
this Brocade device’s perspective of the session, not the neighbor’s 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.
•
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 Brocade 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 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 keep alive time, which specifies how often this Brocade device sends keep
alive messages to the neighbor.
HoldTime The hold time, which specifies how many seconds the Brocade device waits for a
KEEPALIVE or UPDATE message from a BGP4 neighbor before deciding that the
neighbor is dead.
PeerGroup The name of the peer group the neighbor is in, when 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 Brocade device accepts from this
neighbor.
RemovePrivateAs Whether this option is enabled for the neighbor.
RefreshCapability Whether this Brocade device has received confirmation from the neighbor that
the neighbor supports the dynamic refresh capability.
CooperativeFilteringCapability Whether the neighbor is enabled for cooperative route filtering.
