hi Roman,
I would propose BGP on CE-PE link, with some BGP community policy. Then the customer would send you community strings which govern
local preference and announcements of those prefixes.
I made several such policy implementations based on Easynet BGP policy: http://lg.easynet.net/bgppolicy.php This is a very detailed document, and it covers all possible needs for an SP. Typically you only need to implement a part of it.
cheers, stan

Hey All
Quick question: do you allow/run routing protocols between your (isp-) network and your customer? If so: which protocols? If not: what reasons do you tell the customer?
In particular I am interested to know about setups when they want to announce the prefix/subnet you assigned them from your PA-space back to you because they want to run redundant routers.
The setup would probably look like this:
Customer Subnet 10.0.0.0/27 / \ | | [customer router a] - <routing protocol x> - [customer router b] | | <routing protocol y> <routing protocol y> | | [isp router a] - <routing protocol z> - [isp router b] | | \ / ISP Network 10.0.0.0/8
