A piece of iron for BGP?

Question

network hardware

We need a relatively inexpensive solution, about 200 Mbit / sec traffic, a small provider and a dozen of our own servers with projects.
Two optical channels are connected - the main and the reserve. The piece of iron should be able to switch between channels if one of them falls.
Quality iron.

Answer 1

A router on freebsd (+ optical-to-copper converters) will be the most inexpensive solution.

Answer 2

it also depends if you will use the full table and how many vrfs.
"..For full BGP routes, you should consider a router that can take at least 256MB RAM. I am working with a pair of 7206VXRs (NPE-G1) to separate ISPs, and each router is using around 161MB of the installed memory ( 1GB).At least 100MB of that 161MB is tied up by BGP..."
"the 3845 is higher thruput than 720x / NPE-400.
the interfaces are a bit cheaper on the 3845 as well.
also - last time i checked the 3845 was the smallest / cheapest box that can
take dual power supplies."

Answer 3

For example, the 72nd tsiska, you can use it:

Answer 4

Mikrotik RB1100AHx2 worked perfectly for a year up to 250 Mbps traffic. I kept BGP Full View, NAT, Firewall on stable software 5.xx
You can take a piece of hardware that is twice as expensive and pulls more than a gigabit: http://routerboard.com/CCR1016-12G
But there is also raw software 6.xx, which has a lot of glitches .
