Abstract
Indirect destination determinations for forwarding tunnel network packets may be performed. Tunneling may be initiated for network packets received at a packet processor according to a forwarding route or other prior packet processing stage, such as an access control list stage. A corresponding entry in a tunnel lookup table may be accessed to determine the tunneling to be applied to the network packet, such as Internet Protocol tunneling or Multiprotocol Label Switching tunneling. The corresponding entry may also include a pointer to a next hop address table that stores a next hop address for the tunneled version of the network packet. The tunneled version of the network packet may be forwarded to the next hop address.
