IPv4 lookup node.

Node Identifier:
ip4-lookup

This is the main IPv4 lookup dispatch node.

Parameters
vmvlib_main_t corresponding to the current thread
nodevlib_node_runtime_t
framevlib_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 rewrite node.

Node Identifier:
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.

Parameters
vmvlib_main_t corresponding to the current thread
nodevlib_node_runtime_t
framevlib_frame_t whose contents should be dispatched
Graph mechanics: buffer metadata, next index usage

Uses:

  • vnet_buffer(b)->ip.adj_index[VLIB_TX]
    • 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.
  • adj->rewrite_header
    • Rewrite string length, rewrite string, next_index

Sets:

  • b->current_data, b->current_length
    • Updated net of applying the rewrite string

Next Indices:

  • adj->rewrite_header.next_index or ip4-drop
