Usage
Guidelines
The show ip bgp vpnv6 neighbors command displays BGP4+ configuration information and
statistics for IPv4 neighbors with VPNv6 capability negotiated.
Command
Output
The show ip bgp vpnv6 neighbors command displays the following information:
Output field Description
IP Address The IP address of the neighbor.
AS The AS the neighbor is in.
EBGP or IBGP Whether the neighbor session is an IBGP session, an EBGP session, or a
confederation EBGP session:
•
EBGP – The neighbor is in another AS.
•
EBGP_Confed – The neighbor is a member of another sub-AS in the same
confederation.
•
IBGP – The neighbor is in the same AS.
RouterID The neighbor’s ID.
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.
