Also, you don't really need to carry a full BGP table in FIB on a 
Metro-E router. That is one of the reasons it can remain cheap. You just 
need a reasonable amount of FIB slots.

The ASR920 tops out at 20,000 for IPv4 and 4,000 for IPv6. That is not 
enough just for the IGP.

The ACX7024 will do 128,000 for IPv4 and 64,000 for IPv6. That is loads 
better.

You can restrict what BGP routes are installed into the FIB, on any 
modern router OS.

Mark.
