Function Documentation

◆ bd_add_bd_index()

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
bdmbd_main pointer.
Returns
The bridge domain index in l2input_main->l2_bridge_domain_t vector.

◆ bd_add_del_ip_mac()

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.
