Is there a way to summarize E1 or E2 routes at a ABR? I cannot summarise this routes at the ASBR because the ASBR's are Dialin and VPN Endpoints which use the same B-Class Subnets therefor I would like to summarize this Network when it goes over to area 0. Area Range and Area Filterlist don't work for me because this commands only influenze Type 1-3 propagtion, and summary adresse can only be implemented on the ASBR, which is not possible because the DIAL-Users get RADIUS assigned IP's. I'm using Cat6K's with Sup720, IOS 12.2(18) SXE4.
I think you should make ABR an ASBR by adding a static route say 172.16.10.0/29 w/ next-hop towards your VPN end point router & redistribute that static route into OSPF which will make ABR an ASBR, now you can easily use summary-address command to summarize class-B prefixes.
Correct me if i misunderstood your problem.

Thanks for all your replys, ok, some more details: I have a local pool on each RAS/VPN Device with the address 10.31.1.0/24 on the first, 10.31.2.0/24 on the second and so on. All these devices function as ASBR as they redistribute thouse routes in OSPF area 16. There are also some other 10.31.x.x/24 subnets in this area. What I want ist to summarize this Network with 10.31.0.0/16 on the ABR to area 0. As thouse networks are learned via redistributen, they are Type 5 LSA. Unfortunately I can insert this networks with a "network" statement, that doesn't work on my RAS/VPN devices (AS5350 and VPN3030).
Add static route on the ABR for these other subnets(10.31.x.x/24) as you mentioned, with next hop pointing to the device from where these subnets are coming. In the second step redistribute these static routes into OSPF making this ABR an ASBR. After doing this you can apply summary-address command to summarize these other subnets....
