VIRTUAL ROUTER REDUNDANCY PROTOCOL FOR SCALABLE DISTRIBUTED DEFAULT ROUTING GATEWAY

摘要

A VRRP router group can operate in either a standard VRRP mode or a distributed gateway mode in which all VRRP routers generate VRRP control packets but transmit those packets only to local access network-side hosts. The rate of VRRP control packet generation may be decreased in the distributed gateway mode relative to the standard mode. Moreover, VRRP router CPUs may cease processing of VRRP control packets in the distributed gateway mode.

主权项

1. An apparatus comprising:
a plurality of host devices associated with a first access network; and a plurality of routers associated with the first access network, the routers implementing a first mode of operation in which each of the routers of the plurality of router generates virtual router control packets.
