HI, [Pls Rate if HELPS]

CISCO 7200 with NPE-G1 is recommended if you are going to receive full Internet Routing Table from the Service Provider, since current Internet Routing Table size is around 2 Lakh 48 Thousand Prefixes.

509K bytes of NVRAM is recommended. BootFlash: size is recommended based on the IOS Software file size.

Note: If you are going to receive only the DEFAULT from the Service Provider, then your ROUTER is more than Enough.

I am attaching a sheet about the Router Performance Measurement for CISCO Routers.

Hope I am Informative.

Pls Rate if HELPS

Best Regards,

The memory and flash looks fine, it will meet your needs, connecting you to a single ISP. One question though: which type of NPE do you have?

The 7200 with NPE-G1 or NPE-G2 is/was used by many enterprise customers and even in service provider networks to carry the full internet routing table.

It's not clear whether you have an NPE-300,400,G1... However, since you only have a single upstream transit provider, you don't need to carry a full bgp table. Ask your provider to send you a default route (0/0) and their internal routes only. This will reduce the amount of CPU + memory required.
