Hi Aaron,

This is the test scenario I built.

https://null.53bits.co.uk/index.php?page=isis-basic-multi-topology

It was a about 6 months ago and I've been absolutely flat out this
year. I was planning to get the latest vMX version to see if anything
was in there and get back to exploring SR with XRv and vMX but I
haven’t had any time. I haven’t even checked what the state of SR on
Junos is. Failing that I’ll have to use the $dayjob lab if it needs
hardware support.

If SR is in any Junos version and you managed to test anything, please
post back to the list :)

Cheers,
James.
