Abstract

Control traffic in a virtual LAN (VLAN) may be reduced. In one implementation, a network device may implement one of a plurality of redundant gateway devices in a virtual router that includes one or more other network devices, where the network device and the one or more other network devices are associated with a first address that corresponds to the virtual router. The network device may filter egress traffic to drop egress traffic that includes a particular destination address and that is at an interface of the device that is not needed to deliver control traffic.

First claim

What is claimed:

1. A network device comprising:
a plurality of interfaces associated with communication links through which the network device communicates; and
one or more processors to:
control the network device to act as one of a plurality of physical devices in a virtual router that implements a redundant gateway for a virtual local area network (VLAN),
the network device being a member of the VLAN;

determine one or more inactive interfaces, of the plurality of inter…
