instance. Use the no form of this command to disable authentication.

Functional Notes
The password command can be used to specify the authentication password used for TCP
communication with this BGP neighbor on either the default or nondefault VRF instance. If the neighbor is
to be created on a nondefault VRF instance, the VRF instance must first be created using the command
<name> route-distinguisher on page
configure the BGP neighbor settings for the VRF instance using the command
from the router's BGP Configuration mode. For example, to configure the BGP neighbor characteristics for
the nondefault VRF instance RED1, enter the following commands:
(config)#vrf RED1 route-distinguisher ip 192.17.250.24:33
(config)#router bgp 100
(config-bgp)#vrf RED1
(config-bgp-vrf)#neighbor 10.20.1.1
(config-bgp-vrf-neighbor)#
For more information about VRF and Multi-VRF BGP configuration, refer to the configuration guides

18.03.00/R10.1.0 or Later (article number 3524) available online at https://supportforums.adtran.com.
Authentication must be configured on both peers using the same password. Every BGP TCP segment sent
is authenticated. Configuring authentication causes an existing session to be torn down and re-established
using the currently specified authentication.
