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.

mms 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.
Hi Daniel,
MAC address is 48 bits long. For Multicast MAC address, the first 24 bits
is 01-00-5e. The next bit is set to 0. That leave you with 23 bits.
48-24-1=23.
In your example, 224.138.8.5
1110 1000 1010 1000 0101
X000 1010 1000 0101
