Hi
At on http://www.solarwinds.com/Orion Platform 2016.2.100, NCM 7.5, IVIM 2.1.2, NetPath 1.0.1, NPM 12.0.1, We are monitoring gre tunnels between our core Juniper SRX Junos firewall and ISP, problem is that -even if the router on the other end is down, tunnel still shows green and up.
when see the interface status... its always up ... but when we go in deep and show interface detail ..its show Gre keepalives adjacency state which show the real status i.e. Down or Up, Screen shot attached of NMS and the configuration for your ready reference.
Please guide further.
