My two border routers are set to be returned off lease in a few months, and am just getting around to budgeting the new ones. I wanted to come here to get a general feeling of what I should replace my current equipment with.
Right now we have some outdated 7301s that we are using. They are strictly acting as routers, and terminating 3 VPN tunnels. There are no additional services that we are running on them, no QoS, no voice services; some security, but nothing too extensive. I don't see the need to go out and replace these with the high-end 7200s if the main requirement is that we have is enough Memory for full BGP routing tables.
One router is using a partial T3 connection, and the other one is on rate-limited ethernet. The tunnels are moving off, and we have other devices for our IPS and Security function. These are going on a 3 year lease, with not that much growth projected over that time-frame. We service close to 1000 persons internally, host several public websites, and of course demand 100% uptime and high reliability, but I think we can achieve that using a 3800 series rather than going with the 7200. It would be nice if I can free up some money to budget else where.
