We are currently in the planning stages. In the initial phase, we're looking at 6 servers (2 Varnish, 2 web and 2 database). The Data Center we're planning on going with states they have "blended, Multi-Homed Bandwidth (Redundant uplinks for HSRP, BGP, Performance Routed)".
From what research I've made so far, HSRP is proprietary (Cisco), and BGP is a bit over my head. I'm not a fan of Cisco, but I'll consider it if I need to in order to maintain the redundancy.
My preference of router manufactures, based purely on gut feeling at this point, are HP, pfSense, Cisco, MikroTik (in that order), but I'll look at anything.
What routers would you recommend? Our budget is flexible, but I would prefer to stay as close to $1K/router as possible.
