Hi GS,

R1|F0/0------F0/1|R2|F0/0-----F0/0|R3|F0/1|1.1.1.1

When R1 sends a unicast packets with destination address 1.1.1.1, and when
packet arrives on R2
before doing IP lookup does it checks for destionaton MAC address from
incoming packet.

If it checks for the dest. MAC add. should it needs to match with MAC of
R2's incoming interface address.

What if it is not match with incoming interface? as in multicast the Dest.
MAC address in incoming packet is Multicast
MAC address.
