Function Documentation

adj_index_t adj_mcast_add_or_lock	(	fib_protocol_t	proto,
		vnet_link_t	link_type,
		u32	sw_if_index
	)

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

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

void adj_mcast_module_init

(

void

)

Module initialisation.

void adj_mcast_update_rewrite	(	adj_index_t	adj_index,
		u8 *	rewrite
	)

Update the rewrite string for an existing adjacecny.

Parameters

The	index of the adj to update
The	new rewrite

Update the rewrite string for an existing adjacecny.

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.
