Description
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.
Options
| authentication | Authentication scheme: |
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).
Required Privilege Level
