Hello,
I have am having an issue with a remote site redundant IPSEC tunnel config. When the remote site is on the primary IPSEC tunnel, the traffic from Host A to Host B is successful. When the primary link fails, the second tunnel can be established but host to host communication fails. I should mention that when I initiate the fail over at the remote site by pulling the plug, I have to run packet tracer to get the tunnel to come over the backup ISP. The tunnel is created and the SA is active however the host traffic does not get reassigned. I am using an SLA and a track to test reach ability and remove the static route. The remote host's DG is the inside interface of the remote fw. Could anyone shine some light on what I may be missing. Here is the config and I appreciate any help.
Thanks,
