Re: [Lsr] Temporary addition of links to flooding topology in dynamic flooding

+1 Les. In general - in ECMP cases LFA is meaningless (any ECMP member is loop-free per definition) so commonly used technology is fast-rehash, where in case of failure all the flows that would use the link in question are rehashed over other links in the bundle and that is done in HW. Regards
