I am trying to make this work, I have a 9k in the middle that should bridge this together but I cant ping through.

Solved! Go to Solution.

That led me to solution, Dang.. Everything was setup correct on router.. Turns out the edge device did not have a return route. Added static and now all is good. I never looked at the interface counters, that was the key. Traffic was going out and not getting back in.

Hi!
Are you sure that vlans are correctly configured in both Edge and the Junos Switch?
Best Regards.

Vlans are set correct, Everything Pings.. I just cant Ping from source interfaces. Its almost like I can not use L2vpn bridge in a source ping. As matter of fact, I can ping the interface 172.16.0.1 from 10.x just cant get to 172.16.0.2 - 254.

Is this a physical asr9k ? or a virtual asr9kv ?
when you ping can you check show interface counters (before and after) to see if packets are exiting the router
