Closing Or Resetting A Neighbor Session - Foundry Networks FESX Manual

rows under Refresh-Req indicate how many dynamic refreshes have been sent to and received from the neighbor.
The statistic is cumulative across sessions.

Closing or Resetting a Neighbor Session

You can close a neighbor session or resend route updates to a neighbor.
If you make changes to filters or route maps and the neighbor does not support dynamic route refresh, use these
methods to ensure that neighbors contain only the routes you want them to contain.
• If you close a neighbor session, the Layer 3 Switch and the neighbor clear all the routes they learned from
each other. When the Layer 3 Switch and neighbor establish a new BGP4 session, they exchange route
tables again. Use this method if you want the Layer 3 Switch to relearn routes from the neighbor and resend
its own route table to the neighbor.
• If you use the soft-outbound option, the Layer 3 Switch compiles a list of all the routes it would normally send
to the neighbor at the beginning of a session. However, before sending the updates, the Foundry Layer 3
Switch also applies the filters and route maps you have configured to the list of routes. If the filters or route
maps result in changes to the list of routes, the Layer 3 Switch sends updates to advertise, change, or even
withdraw routes on the neighbor as needed. This ensures that the neighbor receives only the routes you want
it to contain. Even if the neighbor already contains a route learned from the Layer 3 Switch that you later
decided to filter out, using the soft-outbound option removes that route from the neighbor.
