DHCPv6 Relay Agent on ACX Series Routers
The DHCPv6 relay agent enhances the extended DHCP relay agent by providing DHCP support in an IPv6 network. DHCPv6 relay agents eliminate the necessity of having a DHCPv6 server on each physical network. An ACX Series router configured as a DHCPv6 relay agent passes messages between the DHCPv6 client and the DHCPv6 server, similar to the way a DHCP relay agent supports an IPv4 network.
The DHCPv6 relay agent is compatible with the extended DHCP local server and the extended DHCP relay agent, and can be enabled on the same interface as either the extended DHCP local server or DHCP relay agent.
To configure a DHCPv6 relay agent on the ACX Series routers, include the dhcpv6 statement at the [edit forwarding-options dhcp-relay] hierarchy level. You can also include the dhcpv6 statement at the [edit routing-instances routing-instance-name forwarding-options] hierarchy level.
Use the following operational commands to verify and manage DHCPv6 relay agent settings:
clear dhcpv6 relay binding
clear dhcpv6 relay binding routing-instance routing-instance-name
clear dhcpv6 relay statistics
clear dhcpv6 relay statistics routing-instance routing-instance-name
show dhcpv6 relay binding
show dhcpv6 relay binding routing-instance routing-instance-name
show dhcpv6 relay statistics
show dhcpv6 relay statistics routing-instance routing-instance-name
The following DHCPv6 functionalities are not supported on ACX Series routers:
Subscriber authentication for DHCPv6 relay agents
DHCP snooping
DHCPv6 client
Liveness detection
Dynamic profiles
Option 37 support for remote ID insertion
Bidirectional Forwarding Detection (BFD) for DHCPv6 relay
DHCPv6 relay persistence on router reboot, or crash, or power failure
