We have configured GRE tunnels between few routers. Few tunnels, go down very frequently due to recursive routing. As per the link below, we gave a static route with /32 mask via the next hop interface. This resolves the recurssive routing issue. Though the tunnel status is up and stable, will not be able to ping the device.
If we change the next hop to other end tunnel ip, recurssive routing occurs and and when the tunnel is up, will be able to ping the device.
Kindly advise on resolving this issue.
Thanks in advance
