Technology VRRP Introduction Reference Virtual Router Redundancy Protocol (VRRP) is an error-tolerant protocol that provides highly reliable default links on multicast and broadcast LANs such as Ethernet, avoiding network interruption due to failure of a single link. "Configuring VRRP" in High Availability Configuration Guide A single availability technology cannot solve all problems. Therefore, a combination of availability technologies, chosen on the basis of detailed analysis of network environments and user requirements, should be used to enhance network availability. For example, access-layer devices should be connected to distribution-layer devices over redundant links, and core-layer devices should be fully meshed. Also, network availability should be considered during planning prior to building a network. 4
