That's 1M IPv4 routes, IIRC. Put IPv6 into the mix and that 1M quickly shrinks.

I am researching possible replacements for our Internet edge routers, and wanted to see what people could recommend for a smaller chassis or fixed router that can handle current IPv4 routes and transition into IPv6. Currently we have Brocade NetIron 4802s pulling full IPv4 routes plus a default route. I've looked at Extreme, Brocade, Cisco, and a few others. Most range from 256k - 500k IPv4and4k - 16k IPv6 routes when CAM space is allocated for both. The only exception I've found so far is the Cisco ASR 1002, which can do 125kv6along with 500k v4 routes at once. I'm curious if any other vendors have comparable products.
Mx80 Doesn't use CAM for route lookups and the actual number of routes is 72MB of RLDRAM holds will vary based on the distribution of sizes but it's north of 2 Million ipv4 routes.
The NetIron XMR will get you 1,000,000 routes.
