VRF
•
default-vrf – The L2VPN is only applicable to the global default VRF
instance.
State The state of the Brocade device’s session with the neighbor. The states are
from this 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.
•
ADMND – The neighbor has been administratively shut down.
•
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.
State (cont’d) Operational States:
Additional information regarding the operational states of the BGP states
described above may be added as described in the following:
•
(+) – Indicates that there is more BGP data in the TCP receiver queue.
•
(-) – indicates that the session has gone down and the software is
clearing or removing routes.
•
(*) – indicates that the inbound or outbound policy is being updated for
the peer.
•
(s) – indicates that the peer has negotiated restart, and the session is
in a stale state.
•
(r) – indicates that the peer is restarting the BGP connection, through
restart.
•
(^) – On the standby MP indicates that the peer is in the ESTABLISHED
state and has received restart capability (in the primary MP).
•
(<) – Indicates that the Brocade device is waiting to receive the “End of
RIB” message from the peer.
Time The amount of time this session has been in its current state.
KeepAliveTime The keep alive time, which specifies how often this 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.
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.
