Re: Force10 E Series at the edge?

I was very happy with the E300 as a data center core switch handling multiple full feeds (around 15) with about 10x the 
traffic you are talking about.  The only problem I had was that Force10 didn't have a useful (basically forklift) 
upgrade to get more IPv4 prefixes, and the more I talked to them and the more I showed them the graphs demonstrating 
what we'd need for prefix space assuming even the most conservative assumptions at depletion, the more I realized they 
really Did Not Get It.  In fact, their brand new architecture recently announced had only 500k prefixes allowed, at a 
time that the Juniper MX platform handled 2million easily.

So I would be fine using Force10 again, given the following changes:
        1. Large limits on IP prefixes allowed
        2. Reallocation of useless memory from stupid things like MAC tables to prefixes (data centers have very few 
MACs, very many prefixes)
        3. Command line logging 

The units worked great at failover, never had any problems gracefully failing over from one RP to another, but if you 
have to cold boot them for any reason it takes like 5 minutes :(

Is anyone running an E300 Series Chassis at the internet edge with multiple Full BGP feeds? 95th percent would be 
about 300 meg of traffic. BGP session count would be between 2 and 4 Peers.
6k internal Prefix count as it stands right now. Alternative are welcome. Thought about the ASR1006 but I need some 
local switching as well.

Full requirements include
Full internet Peering over GigE Links.
Fully Redundant Power
Redundant "Supervisor/Route Processor"
Would prefer a Small Chassis unit. (under 10u)
Would also prefer a single unit as opposed to a two smaller units.
