Parameters
relay: Enables the DHCPv6 relay agent on the interface.

Usage guidelines
Before changing the DHCPv6 server mode to the DHCPv6 relay agent mode on an interface, use the
reset ipv6 dhcp server ip-in-use and reset ipv6 dhcp server pd-in-use commands to remove IPv6
address/prefix bindings.
An interface cannot serve as the DHCPv6 relay agent and the DHCPv6 server at the same time.
