IPv4 lookup node.

Node Identifier:

ip4-lookup

This is the main IPv4 lookup dispatch node.

Parameters

vm	vlib_main_t corresponding to the current thread
node	vlib_node_runtime_t
frame	vlib_frame_t whose contents should be dispatched

Graph mechanics: buffer metadata, next index usage

Uses:

• vnet_buffer(b)->sw_if_index[VLIB_RX]
  • Indicates the sw_if_index value of the interface that the packet was received on.
• vnet_buffer(b)->sw_if_index[VLIB_TX]
  • When the value is ~0 then the node performs a longest prefix match (LPM) for the packet destination address in the FIB attached to the receive interface.
  • Otherwise perform LPM for the packet destination address in the indicated FIB. In this case [VLIB_TX] is a FIB index value (0, 1, ...) and not a VRF id.

Sets:

• vnet_buffer(b)->ip.adj_index[VLIB_TX]
  • The lookup result adjacency index.

Next Index:

• Dispatches the packet to the node index found in ip_adjacency_t adj->lookup_next_index (where adj is the lookup result adjacency).

IPv4 local rewrite node.

Node Identifier:

ip4-rewrite-local

This is the IPv4 local rewrite node. Fetch the ip adjacency, check the outbound interface mtu, apply the adjacency rewrite, and send pkts to the adjacency rewrite header's rewrite_next_index. Deal with hemorrhoids of the form "some clown sends an icmp4 w/ src = dst = interface addr."

Parameters

  • the rewrite adjacency index
• adj->lookup_next_index
  • Must be IP_LOOKUP_NEXT_REWRITE or IP_LOOKUP_NEXT_ARP, otherwise the packet will be dropped.

Here is the call graph for this function:

static uword ip4_rewrite_transit ( vlib_main_t *  vm, vlib_node_runtime_t *  node, vlib_frame_t *  frame  )

static

IPv4 transit rewrite node.

Node Identifier:

ip4-rewrite-transit

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.

Parameters

vm	vlib_main_t corresponding to the current thread
node	vlib_node_runtime_t
frame	vlib_frame_t whose contents should be dispatched
