Enable Virtual Router Redundancy Protocol (VRRP) IPv4 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. The specific type of authentication used by OSPF is encoded in this field.
All devices in the VRRP group must use the same authentication scheme and password.
When VRRPv3 is enabled, the authentication-type and authentication-key statements cannot be configured for any VRRP groups.
- simple—Use a simple password. The password is included in the transmitted packet, so this method of authentication is 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 routing platform 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).
