What does DHCP relay mean?
A DHCP relay agent is a host or router that forwards DHCP packets between clients and servers. Network administrators can use the DHCP Relay service of the SD-WAN appliances to relay requests and replies between local DHCP Clients and a remote DHCP Server.
What is IPv6 relay?
Enables the IPv6 DHCP relay agent function and specifies the IPv6 address as a destination address to which the client messages are forwarded.
What type of message does a DHCP relay listen to?
IP broadcast messages
The DHCP Relay Agent allows to place DHCP clients and DHCP servers on different networks. Deploying DHCP in a single segment network is easy. All DHCP messages are IP broadcast messages, and therefore all the computers on the segment can listen and respond to these broadcasts.
What is DHCP and DHCPv6?
The differences are that DHCPv6 uses Unique Identifiers, while DHCP uses MAC addresses to identify the client. DHCP messages are transmitted over IPv4 packets and DHCPv6 is transmitted over IPv6 packets. DHCPv6 uses Router Advertisement (RA) and IPv6 multicast messages and DHCP uses broadcast IPv4 messages on the LAN.
Which two messages are sent out by the DHCPv6 server?
A normal DHCPv6 message exchange involves the following messages: 1. Solicit – sent by a DHCPv6 Client to locate DHCPv6 Servers. 2. Advertise – sent by a DHCPv6 server to a DHCPv6 Client in answer to the solicit message as an affirmative message that DHCPv6 Server services are available to a DHCPv6 Client.
Why do we need DHCP relay?
A DHCP relay agent sits between a DHCP server and DHCP clients and allows the DHCP clients to obtain IP addresses from the DHCP server that is not configured on the same LAN.
Should I turn on DHCP relay?
DHCP relay is essential when you need the DHCP server to serve addressed to machines not in the same subnet.

How does IPv6 DHCP work?
DHCPv6 is a method to assign IPv6 addresses automatically to network clients. When you enable IPv6 for a trusted or optional interface, you can enable the DHCPv6 server on the interface, to assign IPv6 addresses to clients that connect. Before you can enable the DHCPv6 server, you must enable IPv6 for the interface.
