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 inherits 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:
%STKUNIT0-M:CP %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:
%STKUNIT0-M:CP %KERN-6-INT: BGP MD5 password mismatch from
[peer's IP address] : 11502 to [local router's IP address] :179
