You are absoklutly right. There is no errata because I have also checked.
What I meant to say is a typo or an error!
Sorry for the confusion.

I am studying for the switching exam and I am converting ip multicast
address to ethernet addresses.
What i don't get is that they state in the Cisco press book (page 294/295)
"the least 23 least significant bits of the ip multicast group are place
into the frame..."
"half of the ethernet

The 48-bit ethernet address should read:
0001 0101 1110 0 which converts to 01:00:5e This leaves
23 bit that can be matched to the Ip Multicast least-significant
23 bits.
ok ok ok!!! some of you might think that I was in left field. I think I know
where I went wrong.
I am mixing the 48-bit ethernet address with the conversion process. Let me
explain:
I was adding a full "half octet field" 01:00:5e:0 when it is actually just
one bit (0) from the ethernet address.
will give you 7f:08:0a.
Again, put it together with 01:00:5e will get you 01:00:5e:7f:08:0a.
I hope that this helps.
