I am building a 5 hop microwave network for a city emergency radio infrastructure. I intend to build the system in a circle so that in the event that any one hop were to fail, all the remaining locations would still have a viable path to communicate.
I am guessing I could use routers with 3 Ethernet ports (one for site specific gear, one for one microwave link, one for the other microwave link) and use routing priorities to try one direction first, and if it fails try the other. (Does that make sense?)
I know that the new switches have IOS capabilities, can I do this with a switch? If not, what router can I use?
I haven't done much with Cisco routers for a few years so I'm a little out of touch with what the capabilities are...
Thanks very much for any guidance!
