To summarize your PPPoE pools, the prefix for it needs to be in another area. Depending on your RouterOS version, it will automatically create the blackhole route for the area-range. It's not too difficult, I can send you config samples if you need. No filters needed with area-range and separate area.

You can do the same thing to aggregating part of a hierarchy. So long as the contiguous prefixes are all downstream from a single router, you can put that "leg" of the network into a different area and summarize it using the area-range.

**Queue Bruce about using iBGP for this** (which I support) :)

Mainly the pppoe, but I'd also like to clean up the routing table a bit by summarizing subnets that are contiguous. Maybe I'm over complicating it with that last part.

What are you trying to accomplish?  I’ve never liked summary routes, seems like too much potential for error (or maybe too complex for my simple brain).  If you’re trying to avoid propagating a bunch of /32 routes (like with a PPPoE pool), you can blackhole the subnet to create the summary route and then add a route filter to drop /32 prefixes.

Is the only way to do this by adding another area? Recommendations?
