Configuring BGP4 neighbors
26
• 0 – Disables encryption for the authentication string you specify with the command. The
password or string is shown as clear text in the output of commands that display neighbor or
peer group configuration information.
• 1 – Assumes that the authentication string you enter is the encrypted form, and decrypts the
value before using it.
For more information, refer to “Encryption of BGP4 MD5 authentication keys” on page 776.
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. 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” on page 799.
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.
The route map must already be configured. Refer to ““Defining route maps” on page 801.
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 761. 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 817.
