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
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 |
Definition at line 51 of file adj_mcast.c.
u32 adj_mcast_db_size | ( | void | ) |
Get the sze of the mcast adj DB.
Test purposes only.
Get the sze of the mcast adj DB.
This is only for testing purposes so an efficient implementation is not needed

Update the rewrite string for an existing adjacecny and Convert the adjacency into a midchain.
The | index of the adj to update |
The | new 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.
