F27-BL: No
Rationale
Babel exchanges routing information for the selected IPv6 data plane. Hello/update intervals and neighbor-expiry timers govern routing maintenance; they do not negotiate receiver availability windows that constrain user-data transmission.
Assessment method
Primary normative source and selected adjacency-policy analysis; no execution
Source context
Primary selected protocol specifications; temporal agreement versus timer/path preference
Outstanding qualification
No applies to IPv6/Babel without an added MAC scheduling or application agreement. Locally configured timers and planned device shutdown do not supply the missing bilateral temporal agreement.
