A tunnel might be a way around this, since the tunnel should go down if end-to-end connectivity goes down. I know its extra overhead.
Can you configure the radio to not send keepalives when the link is lost? I'm not much into Radio tech, but it's a idea. This would cause the s0 to lose DTR and go down thus adjusting the HSRP priority. --- Jenny McLeod wrote: > Can you use floating static routes instead? > > JMcL > Mr. Oletu Hosea Godswill, CCNA wrote: > > > > Hi group, > > > > > > Who have used the 'standby track serial 0' command > > before, while configuring HSRP. > > > > I tried it and was disappointed because, my two > > upstream providers are connected via a radio > > (microwave link).
