I don't really understand your topology. 2001-2004 I was involved in 
providing network connectivity to around 2500-4500 users at Dreamhack, 
back then the largest LAN in the world as far as we knew. Back then we 
made do with 2x100FE for 20 computers and the core connectivity was 2xGE. 
I'd say your design seems to fairly similar, but with 2x10GE instead, but 
I'm just guessing from what you wrote.

ASR9k has been used before and will do just fine. Dreamhack has grown a 
bit since I was involved:

Don't forget to provide dual stack (IPv4 and IPv6) connectivity. Limit 
your broadcast domains (I'd say 20-50 users per broadcast domain), and 
make sure you do antispoofing (BCP38) for everybody.
