Usage
Information
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
Also, if you configure different passwords on the two routers, the following message appears
on the console:
%RPM0-P:RP1 %KERN-6-INT: BGP MD5 password mismatch from
[peer's IP address] : 11502 to [local router's IP address] :179
