Looking for routing protocol suggestion.
My network currently has two routers, we'll call them Router A and Router B for the moment. Router A is the default gateway for traffic to the internet with Router B being the backup gateway.
The connection that I am concerned with is the connection to a remote office. Occasionaly, the latency for the connection between the default Gateway and the remote office will jump to about 5 times the usual. However, the backup router's latency will still remain as normal. Both routers' connections are being routed through IP Tunnels. I want to use a routing protocol, on Router A, which will recognise the difference in latency and redirect traffic through the Router B tunnel.
Therefore, I am asking for advice as to which routing protocol I can use that will use latency as a metric as opposed to the current metric of hop count, because being routed through a tunnel, the hop count is only 1 hop.
Hopefully I have explained my query in a manner that is understandable.
thanks in advance for any advice.
