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.
