static

LISP-GPE decap dispatcher.

Node Identifier:

lisp_gpe_input_inline

LISP-GPE decap dispatcher.

Decaps IP-UDP-LISP-GPE header and based on the next protocol and in the GPE header and the vni decides the next node to forward the packet to.

Parameters

[in]	vm	vlib_main_t corresponding to current thread.
[in]	node	vlib_node_runtime_t data for this node.
[in]	frame	vlib_frame_t whose contents should be dispatched.

Returns

number of vectors in frame.
