Configuring BGP4 neighbors
26
NOTE
The route map must already be configured. Refer to “
“Defining route maps”
on page 798.
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
“Configuring a
route reflector”
on page 759. 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
“Using soft reconfiguration”
on page 815.
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”
on
page 787.
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
suppressed neighbor’s routes”
on page 773.
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.
Removing route dampening from suppressed neighbor’s routes
You can selectively unsuppress more-specific routes that have been suppressed due to
aggregation, and allow the routes to be advertised to a specific neighbor or peer group.
Here is an example.
BigIron RX(config-bgp)# aggregate-address 209.1.0.0 255.255.0.0 summary-only
