Description
Use the peer password command to configure BGP to perform MD5 authentication when a TCP
connection is being established with a peer/peer group.
Use the undo peer password command to disable the function.
By default, no MD5 authentication is performed for TCP connection establishment.
Once MD5 authentication is enabled, both parties must be configured with the same authentication
mode and password. Otherwise, the TCP connection will not be set up.
Examples
# In BGP view, perform MD5 authentication on the TCP connection set up between the local router
10.1.100.1 and the peer router 10.1.100.2.
