IPv4 lookup node.
ip4-lookup
This is the main IPv4 lookup dispatch node.
vm | vlib_main_t corresponding to the current thread |
node | vlib_node_runtime_t |
frame | vlib_frame_t whose contents should be dispatched |
Uses:
vnet_buffer(b)->sw_if_index[VLIB_RX]
sw_if_index
value of the interface that the packet was received on.vnet_buffer(b)->sw_if_index[VLIB_TX]
~0
then the node performs a longest prefix match (LPM) for the packet destination address in the FIB attached to the receive interface.[VLIB_TX]
is a FIB index value (0, 1, ...) and not a VRF id.Sets:
vnet_buffer(b)->ip.adj_index[VLIB_TX]
Next Index:
adj->lookup_next_index
(where adj
is the lookup result adjacency). Definition at line 91 of file ip4_forward.c.

IPv4 rewrite node.
ip4-rewrite
This is the IPv4 transit-rewrite node: decrement TTL, fix the ipv4 header checksum, fetch the ip adjacency, check the outbound mtu, apply the adjacency rewrite, and send pkts to the adjacency rewrite header's rewrite_next_index.
vm | vlib_main_t corresponding to the current thread |
node | vlib_node_runtime_t |
frame | vlib_frame_t whose contents should be dispatched |
Uses:
vnet_buffer(b)->ip.adj_index[VLIB_TX]
adj->lookup_next_index
adj->rewrite_header
Sets:
b->current_data, b->current_length
Next Indices:
adj->rewrite_header.next_index
or ip4-drop
