If it’s 100% for redundancy, why not just ECMP defaults and not take a full table?
Well, firstly, ring length may be different on either end. So you can't always guarantee ECMP of traffic to/from the device (without much difficulty such as MPLS-TE). You also can't do hop-by-hop routing based on 0/0 or ::/0 when the ring contains multiple devices also doing the same thing. You'll just create a loop. MPLS-based forwarding is your friend here. But yes, if your device is not in a ring, then your suggestion is fine. Mark.
