摘要： Packet switch operating methods and packet switches provision a plurality of tunnels on a packet switch by associating each of the plurality of tunnels with a packet switch port and by configuring the packet switch to modify packets relayed by the tunnel to include a transport identifier associated with the tunnel. The tunnels of the plurality relay packets when permitted by a tunnel index. The plurality of tunnels and the tunnel index are associated with a virtual interface. The methods and packet switches also permit a first tunnel of the plurality of tunnels to relay packets by configuring the tunnel index to indicate the first tunnel. The tunnel index indicates only one tunnel. The methods and packet switches also enable a second tunnel of the plurality of tunnels to relay packets by configuring the tunnel index to indicate the second tunnel, thereby preventing the first tunnel from relaying packets.

摘要： 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.
