Thanks Aaron!!!

That fixed the mac issue I was facing, that was a really good idea!

I had a pending issue with pings but was able to resolve that by adding the below to both of my PE's.

set logical-systems PE2 routing-instances SPRINT vlan-id none


Once that was done all of my pings worked as expected.

Thanks again Aaron for taking time to take a look at it and hopefully this will help someone down the road.

Hi Craig, I had similar issues when labbing using Lsys combined with Layer 2
types of things like martini l2circuits and vpls...

I think it has something to do with the way lsys logical tunnel interfaces
assign their mac/hardware address... I did solve this a couple different
ways...

When I initially only had one tunnel-service configured, then I created more
lt interfaces and saw that there was an alternating mac address assigned...
so , you just have to make sure you use the *different* mac address for the
L2 endpoints so they don't conflict.  But later I learned to simply add
another tunnel-service to my mx104 lsys environment, then this made it even
more likely that I would have a different mac address...
