Technology Introduction
Virtual Router Redundancy Protocol (VRRP) is an error-tolerant
protocol that provides highly reliable default links on multicast and
VRRP
broadcast LANs such as Ethernet, avoiding network interruption
due to failure of a single link.
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.
