Parameters

documented in RFC 4291 where the address is specified in hexadecimal
using 16-bit values between colons. There are the following types of relay
destination address:

argument for this kind of address.
- Global Unicast IPv6 address. If the interface-id argument is omitted then
the Routing table is used.

destination. If this argument is configured, client messages are forwarded to
the well-known link-local Multicast address
All_DHCP_Relay_Agents_and_Servers (FF02::1:2) through the link to which
the output interface is connected.
