Description

On Fast or Gigabit Ethernet interfaces only, enable Virtual Router Redundancy Protocol (VRRP) authentication and specify the authentication scheme for the VRRP group. If you enable authentication, you must specify a password by including the authentication-key statement in the vrrp-group statement.

All routers in the VRRP group must use the same authentication scheme and password.

Options

authentication—Authentication scheme:

• none—Disable authentication.
• simple—Use a simple password. The password is included in the transmitted packet, making this method of authentication relatively insecure.
• md5—Use the MD5 algorithm to create an encoded checksum of the packet. The encoded checksum is included in the transmitted packet. The receiving router uses the authentication key to verify the packet, discarding it if the digest does not match. This algorithm provides a more secure authentication scheme.

Default: none (No authentication is performed.)

Usage Guidelines
