Auto-configuration  of IPv6 Addresses on the Management Interface Support


IPv6 Stateless Address Auto-configuration (SLAAC)


Like IPv4 addresses, there are a number of different ways that a host can be addressed in IPv6. The two most common in IPv4 are static addressing and dynamic address configuration using the Dynamic Host Configuration Protocol (DHCP). Often the reason DHCP used is that it not only provides a method of dynamically assigning addresses, it also provides a way to assign the host devices other service information like DNS servers, domain names, and a number of different custom information.


SLAAC provides the ability to address a host based on a network prefix advertised from a local network router using Router Advertisements (RA). RA messages are sent by default by IPV6 router. These messages are sent out periodically by the router and include information including:


  • One or more IPv6 prefixes (Link-local scope)
  • Prefix lifetime information
  • Flag information
  • Default device information (Default router to use and its lifetime)


SLAAC is enabled by default on Netvisor One.


When you configure IPv6 address on the management interface during setup, the parameter, assignment, has two options:


  • none — Disables IPv6 addresses.
  • autoconf — Configure the interface with SLAAC.
