daft explains how horizontals are used and that the DF+ backbone is basically collection of special inter-fabric horizontal links

draft already adds some procedures for LIE processing and additional computation .

Good thing is it does NOT change really the flooding scopes/rules since those are the hardest part of the spec to implement correctly as is usual the case for IGPs

if you have alternate proposal, well, there is a WG meet in 2 weeks 😉

Hi Tony,

Thank you for providing this draft!

IMO it's an interesting topic that using RIFT in dragonfly or dragonfly+ topology.

Could you please post the draft figures here for reading the draft easily?

And will you consider using east-west connection between the TOFs?

Though it will change the flooding and computation procedure in RIFT protocol, we think it may be another feasible way.

Thank you very much!

Best regards,

Sandy
