Syntax neighbor {ip-address | peer-group-name} password [encryption-type] password To delete a password, use the no neighbor {ip-address | peer-group-name} password command. Parameters ip-address peer-group-name encryption-type password Enter the IP address of the router to be included in the peer group. Enter the name of a configured peer group. (OPTIONAL) Enter 7 as the encryption type for the password entered. 7 means that the password is encrypted and hidden. Enter a text string up to 80 characters long. The first character of the password must be a letter. You cannot use spaces in the password. Defaults Not configured. Command Modes ROUTER BGP 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 will cause 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 will 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 Command History Version 7.8.1.0 Version 7.7.1.0 Introduced support on S-Series Introduced support on C-Series 350 | Border Gateway Protocol IPv4 (BGPv4)
