Configuring BGP4 neighbors
27
prefix-list <string> in | out specifies an IP prefix list. You can use IP prefix lists to control routes to
and from the neighbor. IP prefix lists are an alternative method to AS-path filters. The in | out
keyword specifies whether the list is applied on updates received from the neighbor or sent to the
neighbor. The filters can use the same prefix list or different prefix lists. To configure an IP prefix
list, refer to
“Defining and applying IP prefix lists”
remote-as <as-number> specifies the AS the remote neighbor is in. The <as-number> can be a
number from 1 – 65535. There is no default.
remove-private-as configures the router to remove private AS numbers from UPDATE messages the
router sends to this neighbor. The router will remove AS numbers 64512 – 65535 (the well-known
BGP4 private AS numbers) from the AS-path attribute in UPDATE messages the device sends to the
neighbor. This option is disabled by default.
route-map in | out <map-name> specifies a route map the device will apply to updates sent to or
received from the specified neighbor. The in | out keyword specifies whether the list is applied on
updates received from the neighbor or sent to the neighbor.
NOTE
The route map must already be configured. Refer to “
route-reflector-client specifies that this neighbor is a route-reflector client of the router. Use the
parameter only if this router is going to be a route reflector. For information, refer to
on page 837. This option is disabled by default.
send-community enables sending the community attribute in updates to the specified neighbor. By
default, the router does not send the community attribute.
shutdown administratively shuts down the session with this neighbor. Shutting down the session
allows you to completely configure the neighbor and save the configuration without actually
establishing a session with the neighbor. This option is disabled by default.
soft-reconfiguration inbound enables the soft reconfiguration feature, which stores all the route
updates received from the neighbor. If you request a soft reset of inbound routes, the software
performs the reset by comparing the policies against the stored route updates, instead of
requesting the neighbor’s BGP4 route table or resetting the session with the neighbor. Refer to
timers keep-alive <num> hold-time <num> overrides the global settings for the Keep Alive Time
and Hold Time. For the Keep Alive Time, you can specify from 0 – 65535 seconds. For the Hold
Time, you can specify 0 or
3 – 65535 (1 and 2 are not allowed). If you set the Hold Time to 0, the router waits indefinitely for
messages from a neighbor without concluding that the neighbor is dead. The defaults for these
parameters are the currently configured global Keep Alive Time and Hold Time. For more
information about these parameters, refer to
“Changing the keep alive time and hold time”
unsuppress-map <map-name> removes route suppression from a neighbor’s routes when those
routes have been suppressed due to aggregation. Refer to
“Removing route dampening from
update-source <ip-addr> | ethernet <slot>/<portnum> | loopback <num> | ve <num> configures
the router to communicate with the neighbor through the specified interface. There is no default.
weight <num> specifies a weight the device will add to routes received from the specified neighbor.
BGP4 prefers larger weights over smaller weights. The default weight is 0.
