AS you stated here transit to customer, the question is, does your
routing table (existing) consists of routing which interfere with the
upstream?

If not, it is simple to filter the routes also to the
downstream/customer to reflect what you will give to him.

If you rely here on only filtering or use bird tables with pipes to
filter is something ... it depends on your requirements.

I normally use bird peer tables and pipe from master with filters to had
a table holding the customer view and also had the chance to filter
directly to/from the customer.

If the customer should follow a different routing policy as your own
routing, then it is bit more complicate, but this is nothing i read on
your messages.
