I used to run E300's and E600's with EF generation RPM's and LC's as my edge with the ipv4-320k cam profile and they worked perfectly, each taking about 4-5 full tables until we broke 320k routes in the fib. Since then, they have been relegated to non-full table distribution layer routers.

If you have EG cards, then you can use the 512k cam profile, but who knows how long that will last. Typically these days I have a number of customers who will pick them up off ebay and use them as an edge where they take on-net prefixes and defaults from myself or their other providers.

They also have no problem running with multiple OSPF neighbors in multiple areas:

Subject: [F10-nsp] Force10 E300 Terascale question

Anybody using Dell/Force 10 E300 Terascale on the edge?
Looking for anyone with actual experience placing one of these in a service provider environment, full BGP tables from provider running iBGP to a mirrored setup to different provider (Dual home to different ISP topology).
Also with E300 running OSPF on the inside to multiple areas.
Appreciate any info.
thanks
-Ryan

Hi Ryan,

Just up front, I do work for Dell, but not the Force10 group. I just have some knowledge of the products from using them.

If your E300 has EG3 (dual CAM) line cards, the default CAM profile should provide 512K IPv4 and 32K IPv6 routes. If you have older line cards, you'll top out at a default of 256K IPv4 routes, or 192K/6K IPv4/IPv6. The CAM profiles are configurable so you might be able to squeeze more out of it, but the IPv4 routing table is currently over 436K prefixes from my network's viewpoint and close to 12K IPv6 prefixes. You probably won't have much breathing room. Even the E600i Exascale platform defaults to 512K IPv4 prefixes and I think it tops out somewhere in the 600's if you adjust the CAM profile. These are great datacenter access layer switches when you only need to feed a limited number of routes or just defaults to them and should work well for that. At the edge of the Internet receiving full routes, you probably won't get too much life out of them before you need to start filtering out longer prefixes or replace it with something else. I've not used them in such a scenario, but they easily support all the required standards to make it work as long as you don't exhaust the CAM.

In OSPF, they'll handle more LSAs than their engineering specs say they will, but they apparently do LIFO LSA processing...a real problem if you have lots of churn. When I ran into this their BU said that their hardware is so fast that they never thought they'd have to worry about it. That was 2011, but I doubt they've changed it since then.
