296 Brocade ICX 6650 Layer 3 Routing Configuration Guide
53-1002603-01
Basic configuration tasks required for BGP4
NOTE
If you want the software to assume that the value you enter is the clear-text form, and to encrypt
display of that form, do not enter 0 or 1. Instead, omit the encryption option and allow the software
to use the default behavior.
If you specify encryption option 1, the software assumes that you are entering the encrypted form
of the password or authentication string. In this case, the software decrypts the password or string
you enter before using the value for authentication. If you accidentally enter option 1 followed by the
clear-text version of the password or string, authentication will fail because the value used by the
software will not match the value you intended to use.
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.
You can configure up to 1000 prefix list filters. The filters can use the same prefix list or different
prefix lists. To configure an IP prefix list, refer to “Defining IP prefix lists” on page340.
remote-as as-number specifies the AS the remote neighbor is in. The as-number can be a number
from 1 through 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 through 65535 (the
well-known BGP4 private AS numbers) from the AS-path attribute in UPDATE messages the Layer 3
switch sends to the neighbor. This option is disabled by default.
route-map in | out map-name specifies a route map the Layer 3 switch 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 “Defining route maps” on page342.
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 “Route
reflection parameter configuration” on page317. 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 BGP4 route table or resetting the session with the neighbor. Refer to
“Using soft reconfiguration” on page 391.
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 through 65535 seconds. For the Hold Time,
you can specify 0 or 3 through 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 page304.
