IXP Manager's route collector configs tags prefixes that would be 
filtered but accepts everything. The major differences between the 
collector and server configs from memory are:

* collector tags what would be rejected but accepts them ultimately
* collector has a single routing table rather than a per-client rib
* collector has explicit "export none;" on all clients.
