Hi, I am hoping someone might be able to help with a small failover issue I am working with.
I have a situation where I am using EVDO as a primary data circuit, with a wic1-am for a backup. Currently I am looking for a forgiving fail-over technique. Routing to a tunnel seems like an obvious choice, but from what I can tell, I can only configure the keepalives and retires for keeping the tunnel up and the route installed. Is there no way to specify that a tunnel should not be placed back into an up/up state until a given number of successful keepalives are consecutively received? Unfortunately, the nature of these wireless data connections is that they aren't simply either up or down, but rather they experience varying degrees of packet loss and I'd like to be able to tailor my route installation/removal to fit what I can use as an acceptable rate of packet success/failure. Any help would be much appreciated as I feel there must be a feature somewhere, not necessarily within tunneling, that I am missing! THANKS!!!
