“Displaying the BGP4+ route table”
Number of Routes
Advertising to All
Neighbors
The total of the RtSent and RtToSend columns for all neighbors.
Number of Attribute

Neighbor Address
The IPv6 addresses of this devices BGP4+ neighbors.
AS#
The AS number.
State
The state of this devices neighbor session with each neighbor. The states are
from this devices perspective of the session, not the neighbor’s perspective.
The state values 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: 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 i s now waiting for either a KEEPALIVE or NOTIFICATION
message. If theVirtual ADX 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 Virtual ADX installed
in the BGP4+ route table. Usually, this number is lower than the RoutesRcvd
number. The difference indicates that this Virtual ADX 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.
