Abstract
Packet switch operating methods and packet switches assign a packet to a virtual interface. The virtual interface is associated with a plurality of tunnels. One of the plurality is designated a primary tunnel configured to accept packets. Other tunnels of the plurality are designated as backup tunnels and are configured to reject packets. The methods and packet switches also determine which of the plurality of tunnels is the primary tunnel and determine a packet switch port associated with the primary tunnel. The methods and packet switches egress the packet via the primary tunnel on the packet switch port associated with the primary tunnel.
