Re: Network Backhaul Fallback and Redundancy
I would suggest that you implement routers at each site using something like OSPF or EIGRP or your favorite protocol. You will need to do some configuration on each router so as to set link costs and what not, so that traffic hits the BH before picking the T-1 route. Using this method, the entire network would be routed, so that in the event of the link between say E and C goes out because 6 and 2 got wiped out the router at E would automatically re-route traffic through B and D. When the router cannot see one another like in this situation, they will exchange routing tables and auto update each other so that the new route is formed.
In the event that the BH or T-1 goes out, the same happens. You will need to program the routers at the BH and t-1 sites so that it passes public ip's properly onto the network in the event that something pukes.
All in all, this is how it should be done anyway. Running a bridged network may be cheaper and easier to do, you run into some serious issues doing such. There are other benefits to this setup, such as enhanced control over the network (traffic) as well as enhanced security. |
