How to map an IP address to a Multicast MAC Adress

751 Views

This BSCI Guide shows three Multicast IP addresses that map to the same Multicast MAC address but I think only two of them do.

IP 230.177.3.5 would not map to 0100.5e40.0305 it would map to 0100.5e31.0305?

Is this a mistake/typo from Cisco? Or am I missing something?

I also think the sentence "Notice that the first two octets can vary in the IP addresses" is not quite accurate.

Shouldn't it say "Notice that the first octet and the first bit of the second octet can vary in the IP addresses"?
