I'm not sure where to begin with this issue. it happened once while live and once while testing on the live system. in a network running a T1 (primary link), and two GRE Tunnels (backup links)and utilizing five routers we get the following. The T1 will fail (moron Cuts a trunk Fiber) and then it switches to the tunnels. did I mention we're using EIGRP for Routing. I'm pretty sure it's setup correctly because when the T1 goes down it fails over to the Tunnel connections. and everything continues normally with the exception of e-mail. for some reason e-mail at the remote site via outlook is interrupted even though you can ping and trace route the exchange server successfully. but then after about thirty to forty five minutes (happened both times) all higher level applications (SQL queries, printing, etc.) sending from remote to main site will stop working, event hough they've been working fine up to that point. what could possibly cause this. i don't know if it's a server issue, routing issue, line issue, bandwidth issue (i doubt this one based on the bandwidth graphs). I'm open to any ideas.
