DHCPv6 Relay
LABEL DESCRIPTION
VID Enter a VLAN ID (between 1 and 4094) to be served with DHCPv6 relay.
LDRA Lightweight DHCPv6 Relay Agent (LDRA) adds information to client DHCPv6 requests
before forwarding them to the DHCPv6 server. Select
enable to add information such as
this system’s host name and the slot, subscriber port, and PVC from which the request
was received. Select
disable to have the system forward DHCPv6 requests for this VLAN
without adding information.
Option37 The required option 18 can only add up to 127 characters of information about the
DHCPv6 requests forwarded for this VLAN. Use option 37 if you need to add extra
information beyond what you configure for option 18.
Option 37 (Remote ID Info) is the DHCPv6 equivalent for the Dynamic Host Configuration
Protocol for IPv4 (DHCPv4) Relay Agent Option's Remote-ID suboption.
Option18
(Interface ID)
Info Option 18 is required for LDRA. Specify the Interface ID information to add to the client
DHCPv6 requests forwarded for this VLAN to identify the interface which received the
client message. For example, use “%hname%slotid%pid%svlan” to add this system’s
host name and the slot, subscriber port, and SVLAN ID from which the request was
received.
Option37
(Remote ID) Info Specify additional information to add to the client DHCPv6 requests forwarded for this
VLAN. For example, use “%ptel%chvpi%chvci%mac” to add the subscriber port’s
configured telephone number, the PVC upon which the request was received, and the MAC
address of the client that sent the request.
