Congure password
You can enable message digest 5 (MD5) authentication with a password on the TCP connection between two BGP neighbors.
Congure the same password on both BGP peers. When you congure MD5 authentication between two BGP peers, each segment of the
TCP connection is veried and the MD5 digest is checked on every segment sent on the TCP connection. Conguring a password for a
neighbor establishes a new connection.
NOTE
: You can secure the VTEP neighbor communications as well using the MD5 authentication.
Congure password
• Congure the password in both the BGP peers in ROUTER-NEIGHBOR CONFIGURATION or ROUTER-TEMPLATE CONFIGURATION
mode. The password provided in ROUTER-NEIGHBOR mode takes preference over the password in ROUTER-TEMPLATE mode. Enter
the password either as plain text or in encrypted format.
– password {9 encrypted password–string|password-string}
