Hi, In fact inline IPv6 BFD is supported for other than link-local addresses starting from 18.1 IIRC. This doesn't help for IS-IS or OSPFv3, though, as those use link-local addresses for adjacencies.
We do have IPv6 BFD enabled for IS-IS but with very relaxed timers compared to IPv4. Haven't seen any issues for a couple of years.
