Function Documentation

u32 bd_add_bd_index	(	bd_main_t *	bdm,
		u32	bd_id
	)

Create a bridge domain.

Create a bridge domain with the given bridge domain ID

Parameters

bdm	bd_main pointer.

Returns

The bridge domain index in l2input_main->l2_bridge_domain_t vector.

Here is the caller graph for this function:

u32 bd_add_del_ip_mac	(	u32	bd_index,
		ip46_type_t	type,
		const ip46_address_t *	ip,
		const mac_address_t *	mac,
		u8	is_add
	)

Add/delete IP address to MAC address mapping.

The clib hash implementation stores uword entries in the hash table. The hash table mac_by_ip4 is keyed via IP4 address and store the 6-byte MAC address directly in the hash table entry uword.

Warning

This only works for 64-bit processor with 8-byte uword; which means this code WILL NOT WORK for a 32-bit processor with 4-byte uword.
