IPv6 DHCP RELAY

IPv6 DHCP relay agent provides a method of relaying/forwarding DHCP and BOOTP requests from a DHCP client and DHCP server on different IP networks. It acts as an interface between DHCP client and the server. The DHCP Relay Agent listens for DHCPv4 or DHCPv6 queries from clients or other relay agents on one or more interfaces, passing them along to upstream servers. When a reply is received from upstream, it is multicast or unicast back downstream to the source of the original request. This page explains about configuring DHCP Relay in zWAN CPE for IPV6.

Network Topology

Pre-requisite

DHCP server config should be disabled/deleted on interfaces which are to be added as part of DHCP relay configuration.

Functionality

The zWAN CPE can be configured for DHCP IPv6 relay by adding the DHCP server IP and the relay interfaces in the zWAN CPE.

Parameters

• Configuration Name: Configuration Name for reference
• Config Status: Configuration Status to enable the particular relay server config
• Port: Listen and transmit on configured port. Default is 547 (Optional)
• LowerLink: Specify the lower network interface/link on which requests will be received.
• UpperLink: Specify the upper network interface/link for forwarding requests.
• Add Interface ID: Force the use of the DHCPv6 Interface-ID option.
• Hop Count: Maximum is 255. Default is 10 (Optional)
