General Information

Summary

Virtual Router Redundancy Protocol (VRRP) implementation in the Wandy RouterOS is

RFC2338 compliant. VRRP protocol is used to ensure constant access to some resources. Two or

more routers (referred as VRRP Routers in this context) create a highly available cluster (also

referred as Virtual routers) with dynamic fail over. Each router can participate in not more than 255

virtual routers per interface. Many modern routers support this protocol.

Network setups with VRRP clusters provide high availability for routers without using clumsy

ping-based scripts.
