Local Dhcp Server - Alcatel-Lucent 7705 Configuration Manual

Configuring IP Router Parameters
The 7705 SAR supports DHCPv6 Relay on access IP interfaces associated with IES. Each
DHCPv6 instance supports up to 8 DHCPv6 servers. For more information on DHCPv6
Relay, refer to the 7705 SAR OS Services Guide, "DHCP Relay".
DHCP Relay Agent Options
DHCP options are codes that the 7705 SAR inserts in packets being forwarded from a DHCP
client to a DHCP server. Some options have additional information stored in suboptions.
The 7705 SAR supports Option 60 and Option 61 as specified in RFC 2132. Option 60 is the
vendor class identifier, which can contain information such as the client's hardware
configuration. Option 61 is the client identifier.
The 7705 SAR supports the Relay Agent Information Option 82 as specified in RFC 3046.
The following suboptions are supported for the base router:

Local DHCP Server

The 7705 SAR supports local DHCP server functionality on the base router and on access IP
interfaces associated with VPRN, by dynamically assigning IPv4 addresses to access devices
that request them. This standards-based, full DHCP server implementation allows a service
provider the option to decentralize IP address management into the network. The 7705 SAR
can support public and private addressing in the same router, including overlapped private
addressing in the form of VPRNs in the same router.
The 7705 SAR acts as a DHCP server only; it does not currently function as a DHCPv6
server.
An administrator creates pools of addresses that are available for assigned hosts. Locally
attached hosts can obtain an address directly from the server. Routed hosts receive addresses
through a relay point in the customer's network.
