Hi All,
Just to add to this. I have setup a GNS3 lab for this, to take the testing off the live environment.
If I add a vyos 1.4 (basically FRR 8.5.2) to the mix, I get a similar error vyos side

Seems like ROS 7 is not correctly implementing opaque areas. Perhaps we need an option under the instance or interface-template to enable opaque lsa's?
From the vyos's ospf neighbor perspective.
R-ID: 10.0.1.1 is ROS7
R-ID: 10.0.1.2 is EOS

I will add a ROS6 to the bench and update the post
