Well at the end I will have BGP for the upstream provider but this part work fine so I have not talk about it in my last email.
I have done a fast schema of my setup: http://step.polymtl.ca/~spock/draft.jpg. The reason I want to use CARP inside is because I want to have a single gateway on my servers. The BGP part will take care of annoncing the routes and taking the good exit point. The CARP part will take care of the gateway for my servers. But OSPF is not able to enter the carp route in the routing table... probably because a route is already there. thanks, Francois Rousseau 2007/4/12, Chris Black <[EMAIL PROTECTED]>:

Not sure I /totally/ understand your architecture, but I think what you need is a carp on the upstream. Chris
