remove-private-as configures the device to remove private AS numbers from update messages the
device sends to this neighbor. The device will remove AS numbers 64512 through 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 and out keywords specify whether the list is applied on
updates received from the neighbor or sent to the neighbor.

NOTE
The route map must already be configured.

route-reflector-client specifies that this neighbor is a route-reflector client of the device. Use the
parameter only if this device is going to be a route reflector. This option is disabled by default.

send-community enables sending the community attribute in updates to the specified neighbor. By
default, the device does not send the community attribute.

shutdown administratively shuts down the session with this neighbor. Shutting down the session lets
you configure the neighbor and save the configuration without actually establishing a session with the
neighbor.

When a peer is put into the shutdown state, ribout routes are not produced for that peer. You can elect
to produce ribout routes using the generate-rib-out option. 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 BGP4 route table or resetting the session with the neighbor.

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 0 - 65535 seconds. For the Hold Time, you can
specify 0 or a number in the range 3 through 65535 (1 and 2 are not allowed). If you set the Hold Time
to 0, the device waits indefinitely for messages from a neighbor without concluding that the neighbor is
non-operational. The defaults for these parameters are the currently configured global Keep Alive
Time and Hold Time.

unsuppress-map map-name removes route suppression from neighbor routes when those routes
have been dampened due to aggregation.

update-source ip-addr | ethernetslot/portnum | loopbacknum | venum configures the device to
communicate with the neighbor through the specified interface. There is no default.

weight num specifies a weight a device will add to routes received from the specified neighbor. BGP4
prefers larger weights over smaller weights. The default weight is 0.

The send-label keyword enables IPv6 label capability for the IPv4 peers.

Removing route dampening from suppressed routes

You can selectively un-suppress specific routes that have been suppressed due to aggregation, and
allow these routes to be advertised to a specific neighbor or peer group.
