Displaying BGP4+ information

EBGP/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 router ID.
State The state of the switch’s session with the neighbor. The states are from 
the switch’s perspective of the session, not the neighbor’s perspective. 
The state values can be one of the following:
• 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. 
NOTE: ACTIVE – BGP4+ is waiting for a TCP connection from the 
neighbor.
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+4 has received an OPEN message from 
the neighbor and is now waiting for either a KEEPALIVE or 
NOTIFICATION message. If the switch 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 messages 
with the neighbor.
NOTE: If there is more BGP data in the TCP receiver queue, a plus sign 
(+) is also displayed. 
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 amount of time this session has been in its current state.
KeepAliveTime The keep alive time, which specifies how often this switch sends keep 
alive messages to the neighbor.
HoldTime The hold time, which specifies how many seconds the switch will wait for 
a KEEPALIVE or UPDATE message from a BGP4+ neighbor before 
deciding that the neighbor is dead.
RefreshCapability Whether the switch has received confirmation from the neighbor that 
the neighbor supports the dynamic refresh capability.
