This object is used to define the appropriate DUID for DHCPv6 Relay Agent. Any communicating device (in dhcpv6 perspective) have a unique DHCPv6 identifier (DUID). According to the RFC 4649, DHCPv6 servers can use the DUID to make decisions about the information such as addresses, delegated prefixes, configuration parameters etc. that the client is to receive. Relay Agent uses the DUID to have a unique remote-id for its enterprise number, as sequence of enterprise number followed by remote-id must be globally unique. DHCPv6 Relay DUID is a user defined parameter so it can be set to any value within defined boundaries. DHCPv6 Relay DUID is a 128 octets long identifier, which can have Link-Layer Address as DUID octets or can have Link-Layer address along with some other parameter having variable octets or can have any sequence of octets representing unique DUID. This Object will be used only if value of fsDhcp6RlyIfRemoteIdOption object is set as DUID (1).
