It works all the time now nexus 93108-EX – I think we just disabled the “feature tunnel “then re-enabled it.
I was testing with an ISR on the same links with no issues. What I am missing is Traceroute hops from the tunnel interfaces. This is for both UDP and ICMP traceroutes. Both the ICMP TTL messages and the port unreachable messages are enabled everywhere in the transit path – as well as under the tunnel interfaces. Any ideas?

When it doesn't work, what exactly doesn't work? Maybe share a few config examples and how you test if it works or doesn't work...

They seem to work about 10 percent of the time. I am going a little mad thinking about where the stars and planets were when these tunnels worked. This is with the source and destination in the global table, and testing the tunnel IP, both in a VRF and in the global table. This has been tested using both loopbacks as a source, and the outgoing interfaces. Although I want to use loopbacks as we are using L3 multi-path. I have searched the bug database I don't see anything strange . going to hit up TAC. Tunnels over the same links on a terminated on ASR920 work fine. Has anyone had any good / bad experiences with tunnels on the 9k?
