Hmm that is interesting.. I would have thought BUM would be in scope. If a node is DF elected and receives BUM and if his ES is down why can he not redirect to NDF? NDF, by virtue of getting traffic on ERL could then bypass the DF election status and forward it to that local ESI..

I will in next rev. * IMHO and FWIW an explicit statement that “BUM is not in-scope of the draft, it is not redirected” would help the readers. It would also help to clarify that bypassing DF Election behavior is not relevant for All-Active and Single Flow-Active redundancy modes. You are correct on the DF-bypass redundancy modes; However for the draft itself I am not typing specific behaviours to load-balancing modes: Backup-DF blocking is bypassed if/when applicable.

I assume you are not redirecting BUM traffic. In what redundancy mode will you need to override the DF election? Is it only for single active and port active? Thanks, Sami
