Yeah in both echo mode and no echo mode, initially control packets are sent to negotiate timers. Whilst technically in echo mode it would be possible to have both nodes using different interval timers (for the fast echo packets), as long as the slow control packet timers match edso the BFD session wouldn't drop, everything should work, however in the RFC it does state that the timers shall be aligned (I can't remember exactly how it works, but if one has higher or lower timers the other adjusts to match so this should never happen).
