interfaces <interface> ip rip authentication

Establishes an authentication method to be used for RIP on an interface.

set interfaces interface ip rip authentication [ md5 md5-key password md5-password | plaintext-password password ]
delete interfaces interface ip rip authentication [ md5 md5-key password | plaintext-password ]
show interfaces interface ip rip authentication [ md5 md5-key password | plaintext-password ]
interface
Mandatory. A type of interface. For detailed keywords and arguments that can be specified as an interface, refer to Supported Interface Types.
md5-key
Optional. An authentication key. This key must be the same on both the sending and receiving systems. The key ranges from 1 through 255.
md5-password
Optional. A password to use in MD5 authentication. This password must be the same on both the sending and receiving systems.
password
Optional. A password to use in simple (plain text) authentication. This password must be the same on both the sending and receiving systems.

Configuration mode

interfaces interface {
	ip {
		rip {
			authentication {
				md5 md5-key {
					password md5-password
				}
				plaintext-password password
			}
		}
	}
}

Use this command to establish an authentication method to be used for RIP on an interface. This authentication is independent of the authentication configured for the RIP area.

In plain text authentication, passwords are sent through the network in plain text. In MD5 authentication, the system uses the Message Digest 5 (MD5) algorithm to compute a hash value from the contents of the RIP packet and the password. The hash value and the MD5 key are included in the transmitted packet, and the receiving system (configured with the same password) calculates its own hash function, which must match.

The authentication parameters must be the same for all routers that are to establish two-way communication within a network. If two routers do not agree on these parameters, they do not consider adjacencies, and disregard communication from each other.

Use the set form of this command to specify an authentication method to be used for RIP on an interface.

Use the delete form of this command to remove an authentication method to be used for RIP from an interface.

Use the show form of this command to display an authentication method to be used for RIP on an interface.
