VRRP-Ev2 overview
VRRP-E is implemented the following differences from RFC 3768 which describes VRRPv2 to provide extended functionality and ease of configuration:
- VRRP-E does not include the concept of an owner device, and a master VRRP-E is determined by the priority configured on the device.
- While the VRRP-E virtual router IP address must belong in the same subnet as a real IP address assigned to a physical interface of the device on which VRRP-E is configured, it must not be the same as any of the actual IP addresses on any interface.
- Configuring VRRP-E uses the same task steps for all devices; there are no differences between master and backup device configuration. The device configured with the highest priority assumes the master role.
Note
VRRP-E is supported on the devices described in this guide. In a mixed-device environment, consult your documentation for the other devices to determine if VRRP-E is supported.
VRRP-E does not interoperate with VRRP sessions.
