command.
Parameters
ip-address Enter the IP address of the router to be included in the peer group.
peer-group-name Enter the name of a configured peer group.
encryption-type (OPTIONAL) Enter 7 as the encryption type for the password entered. 7 means

Usage
Information
This command automatically restarts the neighbor session for the configuration to take effect.
Configure the same password on both BGP peers or a connection does not occur. When you configure
MD5 authentication between two BGP peers, each segment of the TCP connection between them is
verified and the MD5 digest is checked on every segment sent on the TCP connection.
Configuring a password for a neighbor causes an existing session to be torn down and a new one
established.
If you specify a BGP peer group by using the peer-group-name parameter, all the members of the peer
group inherit the characteristic configured with this command.
If you configure a password on one neighbor, but you have not configured a password for the neighboring
router, the following message appears on the console while the routers attempt to establish a BGP
session between them:
%RPM0-P:RP1 %KERN-6-INT: No BGP MD5 from [peer's IP address]
:179 to [local router's IP address]:65524
