Hi,
Customer wants to implement tloc-action feature in order to have backup over Hub vEdge in the middle once direct tunnel between 2 border vEdges is down due to one transport loss.
vEdge-1(Ismaning) should communicate over primary/direct ipsec tunnel to vEdge-3(Duisburg), but when that one is down to go over vEdge-2(Frankfurt) and priv1 transport (priv1=mpls, color restrict).
We made policy below as per config guide (topology and policy also in attachment).
When we apply policy without tloc-action statement we get traffic over vEdge in the middle, so policy works, but we want that behavior only if direct tunnel is down, not unconditionally.
When we add tloc-action backup in policy – all our routes have TLOC unresolved. ☹
Any direction for solving problem? I didn't succeed to find any config example with tloc-action in order to validate our config. :(

So obviously I have a route using fra000 (10.242.188.9 and .10 priv1) as intermediate. But that route is never installed because of:
