Filtering
26
NOTE
The device 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 device 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 device
has sent to or received from the neighbor and indicates whether the device received confirmation
from the neighbor that the neighbor supports dynamic route refresh.
The RefreshCapability field indicates whether this device 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.
