This Field...

Displays...

 

 

Routes Received

How many routes the routing switch has received from the neighbor

 

during the current BGP4 session.

 

• Accepted/Installed – Indicates how many of the received routes

 

the routing switch accepted and installed in the BGP4 route table.

 

• Filtered – Indicates how many of the received routes the routing

 

switch did not accept or install because they were denied by

 

filters on the routing switch.

 

 

Routes Selected as BEST Routes

The number of routes that the routing switch selected as the best

 

routes to their destinations.

 

 

BEST Routes not Installed in IP

The number of routes received from the neighbor that are the best

Forwarding Table

BGP4 routes to their destinations, but were nonetheless not installed

 

in the IP route table because the routing switch received better routes

 

from other sources (such as OSPF, RIP, or static IP routes).

 

 

Unreachable Routes

The number of routes received from the neighbor that are

 

unreachable because the routing switch does not have a valid RIP,

 

OSPF, or static route to the next hop.

 

 

History Routes

The number of routes that are down but are being retained for route

 

flap dampening purposes.
