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
neighbor peer-group (assigning peers)Allows you to assign one peer to an existing peer group.
