To dynamically resend all the Layer 3 Switch’s BGP4 routes to a neighbor, enter a command such as the following:
FESX424 Router(config-bgp-router)# clear ip bgp neighbor 192.168.1.170 soft out
This command applies its filters for outgoing routes to the Layer 3 Switch’s BGP4 route table (Adj-RIB-Out),
changes or excludes routes accordingly, then sends the resulting Adj-RIB-Out to the neighbor.
NOTE: The Foundry Layer 3 Switch does not automatically update outbound routes using a new or changed
outbound policy or filter when a session with the neighbor goes up or down. Instead, the Layer 3 Switch applies a
new or changed policy or filter when a route is placed in the outbound queue (Adj-RIB-Out).
To place a new or changed outbound policy or filter into effect, you must enter a clear ip bgp neighbor command
regardless of whether the neighbor session is up or down. You can enter the command without optional
parameters or with the soft out or soft-outbound option. Either way, you must specify a parameter for the
neighbor (<ip-addr>, <as-num>, <peer-group-name>, or all).
Displaying Dynamic Refresh Information
You can use the show ip bgp neighbors command to display information for dynamic refresh requests. For each
neighbor, the display lists the number of dynamic refresh requests the Layer 3 Switch has sent to or received from
the neighbor and indicates whether the Layer 3 Switch received confirmation from the neighbor that the neighbor
supports dynamic route refresh.
The RefreshCapability field indicates whether this Layer 3 Switch has received confirmation from the neighbor that
the neighbor supports the dynamic refresh capability. The statistics in the Message Sent and Message Received
