DHCPv6 Unicast Address Support
CSCut92596 - DHCPv6 Unicast address support in message exchange.
Applicable Products: GGSN, P-GW, SAEGW
Feature Changes
Use of DHCPv6 Unicast Address Support requires that a valid license key be installed. Contact your local
Sales or Support representative for information on how to obtain a license.

Important
The IPv6 prefix delegation for the requested UE is either allocated locally or from an external DHCPv6 server
by P-GW, GGSN, SAEGW based on configuration at these nodes. Currently, these DHCPv6 messages are
sent to the external DHCPv6 server using multicast address as destination address. In networks where there
are large number of P-GW servers, but less number of DHCPv6 servers, the DHCPv6 messages with multicast
address have to travel through the entire network. This increases load on the network. This feature adds Unicast
address support which enables the operator to send all DHCPv6 messages on unicast address towards external
server using configured address of DHCPv6 server in a DHCPv6 service. The operator need to configure a
CLI to support for client unicast operation to the DHCPv6 Server. By default client-unicast is disabled.

Previous Behavior: Earlier there was no support to send DHCPv6 messages to the server on a unicast address.

Customer Impact: Operators will now be able to send DHCPv6 messages on a unicast address by using the
config CLI mentioned below.

Command Changes
dhcpv6-client-unicast
A new command dhcpv6-client-unicast has been added to the existing command dhcp-client-profile. This
CLI command enables support for client unicast operation to the DHCPv6 Server. By default client-unicast
is disabled.
