RE: Split multicast address in two

Way too much work IMHO.

If asked what the range of multicast addresses is, what would you answer?
Just generically, no specifics given. It would be from 224.0.0.0 to
239.255.255.255. (224.0.0.0/4) Ok, so split it in half.

Whether using an ACL or a prefix-list, the simplest way possible is the
first half and the second half! (224-231 and 232-239)

Keep it simple.

HTH,

Hey there fella,

Unless it told you specifically which addresses to shove where, then there
could be loads of interpretation. Depending on how your mind works - I
would maybe go for odds one way and evens the other.

But I expect in the lab they'll be looking at your master of control and
will tell you exactly what to send where - otherwise the marking scripts
wouldn't work too well ;-)
