FW: Getting pretty close to default IPv4 route maximum for 6500/7600routers.

I botched those numbers.

Let me fix.

According to this countdown:
http://inetcore.com/project/ipv4ec/index_en.html we have 6.41 /8's left. So
that is 107,541,955 IPs.

CIDR - Prefixes
-----------------
/20 - 26,255.36
/21 - 52,510.72
/22 - 105,021.44
/23 - 210,042.88
/24 - 420,085.76

My apologies for my erroneous math, I was off one number making the table.

Johns solution to combine MPLS and IPv4 is the best solution. I would
implement it if I hadn't already rebooted a few days ago.
