Function Documentation

u32 bd_add_del_ip_mac	(	u32	bd_index,
		u8 *	ip_addr,
		u8 *	mac_addr,
		u8	is_ip6,
		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 prcessor with 4-byte uword.
