Set what BGP attributes?

Um, AS path, per your original post. duh!

 

>But i want a set of routes to have AS-PATH prepend.

 

 

 

So what you could match on your outbound prepending route-map?

Um, some metric #s or lsa types (i.e. external 1) may need to prepended or
not.. each type can be a single sequence in a route map. ;)

 

How do you tag routes from one ospf router to another?

Tag them way back in the OSPF network SILLY. Where they originate or are
redistributed!

You mean to tell me all of the OSPF routes come from a network statement or
area range command?

If this CE to PE link is the ONLY place where these routes are coming in WHY
DO you need to AS-PREPEND them?

 

Why don't you just redistribute ospf into BGP? I was originally concerned
you were doing this on the internet bgp table. If you are just dumping these
ospf routes to someones MPLS cloud who cares? Just do it.
