Displaying BGP4+VPNv6 information
You can display the following information about a device’s BGP4+ VPNv6 feature:
• BGP4+VPNv6 neighbor information
• BGP4+VPNv6 routing table information
• BGP4+VPNv6 route label information
• BGP4+VPNv6 summary information
State The state of this neighbor session with each neighbor. The states are from this
perspective of the session, not the neighbor’s perspective. The state values
can be one of the following for each:
•
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: 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 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 packets 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 ipv6 bgp
neighbor ipv6-address command, the TCP receiver queue value will be
greater than 0.
Time The time that has passed since the state last changed.
Accepted The number of routes received from the neighbor that this installed in the
BGP4+ route table. Usually, this number is lower than the RoutesRcvd number.
The difference indicates that this filtered out some of the routes received in the
UPDATE messages.
Filtered The routes or prefixes that have been filtered out.
•
If soft reconfiguration is enabled, this field shows how many routes were
filtered out (not placed in the BGP4+ route table) but retained in memory.
•
If soft reconfiguration is not enabled, this field shows the number of
BGP4+ routes that have been filtered out.
Sent The number of BGP4+ routes that the has sent to the neighbor.
ToSend The number of routes the has queued to send to this neighbor.
