I am currently using the Xrv9K 7.2 image and am considering upgrading to 7.6 to test the new features of SR-MPLS FlexAlgo.
The 7.6 image appears to boot correctly and the interface still looks the same as 7.2, but I am unable to communicate packets. I'm wondering if the interface names are off, so I've tried connecting to the 7.6 hosts using back2back, but none of the interfaces are communicating. Do I need to modify some template? Any advice is welcome,Please. Does anyone tried this?

Thanks, in advance.
