IE Vol 1 Auto-RP Filtering Candidate RPs Complete

Ok, it's obvious whoever wrote this part of the workbook wasn't paying close attention to subnet masks. There are several mistakes here.

To filter, from the mapping agent side, which RPs will be announced for a particular group, use the ip pim rp-announce-filter. The tricky part here is that, the only part is not that an entry required for each RP and its associated groups that should be allowed. An extra entry explicitly denying remaining RPs and groups must be added as well, to prevent rouge RPs.
