Updating route information and resetting a neighbor session
NOTE
The soft-outbound parameter updates all outbound routes by applying the new or changed filters,
but sends only the existing routes affected by the new or changed filters to the neighbor. The soft
out parameter updates all outbound routes, then sends the Layer 3 switch entire BGP4 route table
(Adj-RIB-Out) to the neighbor, after changing or excluding the routes affected by the filters. Use
soft-outbound if only the outbound policy is changed.
To dynamically resend all the Layer 3 switch BGP4 routes to a neighbor, enter a command such as
the following.
Brocade(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 BGP4 route table
(Adj-RIB-Out), changes or excludes routes accordingly, then sends the resulting Adj-RIB-Out to the
neighbor.
NOTE
The Brocade 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 rows under Refresh-Req indicate how many dynamic
refreshes have been sent to and received from the neighbor. The statistic is cumulative across
sessions.
