Why would there be a need to forklift? If the box will not do peering via IPv6, then modify the CAM profile to allocate more memory for IPv4, and that takes care of 500+K IPv4 routes. The key thing here is how many routes are held in the FIB, which holds the best routes after BGP machine runs through its calculations, and as long as the box can hold all of the peer's routes in the RIB-in, then you're ok. Hopefully when we allocate all /8 this year, folks will start moving over to IPv6. With IPv6's aggregation capabilities, you won't need such a large table, so you're ok there. The OP is only doing two BGP sessions, and it seems requires a multitude of GigE ports, so an ASR here gets expensive fast for this type of deployment. I am curious though Mike... what box would you suggest here?
