How DHCP and DHCPv6 work in RouterOS: address assignment, leases and renewal, conflict checks, client identification, options and relays, and which RouterOS component to use: the DHCP client, server and relay for IPv4, and the DHCPv6 client, server and relay for IPv6.
DHCP relay forwards DHCP and DHCPv6 requests from clients to a DHCP server in another network, with optional relay agent information (option 82) and VRF support.
The RouterOS DHCPv6 client requests IPv6 addresses and delegated prefixes (DHCPv6-PD) from a DHCPv6 server, adds received prefixes to IPv6 pools, and can run scripts on status changes.
The RouterOS DHCPv6 server delegates IPv6 prefixes (DHCPv6-PD) and assigns IPv6 addresses to clients, with static bindings, RADIUS support and per-binding rate limiting.
This page demonstrates configuring IPv6 Prefix Delegation over PPPoE in RouterOS, showing how to set up DHCPv6-PD pools on servers and clients, including interface configuration and verification of dynamic prefix delegation.
