A township board needs a remote clinic firewall to receive a delegated IPv6 block from upstream so it can number internal VLANs without manual per-site prefixes. Which mechanism fits?
Select an answer to reveal the explanation.
Short Explanation
Prefix delegation is like the township handing the clinic a block of street numbers to subdivide inside the building. DHCPv6 PD ships that prefix downstream so the firewall can carve internal /64s. You are not stuck typing a unique prefix by hand for every remote site.
Full Explanation
DHCPv6 prefix delegation allows a requesting router (here, the clinic firewall/CE) to obtain a prefix from a delegating router and advertise or assign longer prefixes internally. This scales dual-stack remote sites. IPv4 PAT, multicast RP mechanisms, and per-host NAT66 do not provide hierarchical IPv6 prefix delegation.
