Hi,
As per RFC 2464, Link local address for Ethernet based interfaces are based on
the EUI-64 (derived from the MAC address).
I have #3 questions based on this.
In this case,
when one Ethernet based host(from its link-local source) tries to ping the
other Ethernet based host, it knows the Mac address implicitly (from the Link
local address).
1. Why is it required to explicitly do the Neighbor discovery for the
link-local addresses?
RFC 4861 says to do the neighbor discovery even for link-local addresses.
Correct me if my understanding is incorrect.
2. Does it mean that in Ethernet networks, interface can have only one
Link-local address? If not then we violate the RFC 2464.
3. Does RFC 4941 Privacy extension for autoconf apply to Ethernet interfaces?

Parav Pandit
