Need Multi-Auth Information

[Prasenjit Manna]

Hi,

I want to know some informations regarding How multi-auth works in wired 
setup.
1. What is the destination address of EAPOL packet? Is this unicast or 
group address?
    In single-host mode, Authenticator sends EAPOL-Request/Identity 
packets to wire.
    The same this is applicable here for multi-auth mode? If it is like 
this, then what will be the destination
    address of the first packets from authenticator?


Thanks in advance,
Prasenjit
