Re: multicast and the BSCN - a match made in hell?
I think you mean 224.0.0.5 and 224.0.0.6 which are the LSA multicast's used in OSPF, A good rule to remember is the 224.0.0.XXX subnet is basically used for all router/ routing information. It typically has a TTL of 1 meaning it will get to the first router and not passed on.

Re: multicast and the BSCN - a match made in hell?
As you progress in your studies, the following sites should become your friends. There is much you will not understand. But things will become clear over time. Just keep asking. Just keep reading. www.ietf.org look for RFC's and all kinds of things here www.iana.org internet assigned numbering authority or some such. one of the jump points is the protocol numbers and assignments index. also, those class D addresses you learned in CCNA - you know 224.0.0.0 through 239.255.255.255 here's where you find out kinda how they work. www.arin.net always fun to look stuff up here www.nanog.org lots of good reading to be found. white papers, presentatons, and the e-mail archives.

Dyland, For the test just accept the fact! I just passed BSCN last week and I am studying beyond CCNP. The Cisco web site is a wealth of information. Start using it now and you will be one step closer to becoming a Cisco professional...
