Hi all,
I have small doubt on Multicast MAC address calculation..
What I understand is the lower order 23 bits of multicast ip address will be
used with "01-005E-00-00- 00" to generate multicast MAC address.
But since the multicast ip address range is upto 28 bits of classD I feel
there will be a clash , I mean same Multicast MAC will be generated for
different multicast ip addresses.
If this is the case when there will be a packet to one of the multicast ip
address will it be send to all routers/machines who are having same
multicast MAC??
IF not How will switch differentiate?
Any ideas? or my understanding is wrong?
Thanks in advance
Murali
