Abstract
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.
