Mcast Adjacency.
The multicast adjacency forwards IP traffic on an interface toward a multicast group address. This is a different type of adjacency to a unicast adjacency since the application of the MAC header is different, and so the VLIB node visited is also different. DPO types have different VLIB nodes.
Add (and lock) a new or lock an existing mcast adjacency
- Parameters
-
proto | The protocol for the neighbours that we wish to mcast |
link_type | A description of the protocol of the packets that will forward through this adj. On an ethernet interface this is the MAC header's ether-type |
sw_if_index | The interface on which to mcast |

Return the size of the adj DB.
Get the sze of the mcast adj DB.
This is only for testing purposes so an efficient implementation is not needed

adj_mcast_midchain_update_rewrite
Update the rewrite string for an existing adjacecny and Convert the adjacency into a midchain.
Update the adjacency's rewrite string. A NULL string implies the rewirte is reset (i.e. when ARP/ND etnry is gone). NB: the adj being updated may be handling traffic in the DP.
