Configuring a Global or Site-Local IPv6 Address on an Interface

Configuring a global or site-local IPv6 address on an interface does the following:

  • Automatically configures an interface ID (a link-local address), if specified.
  • Enables IPv6 on that interface.

Additionally, the configured interface automatically joins the following required multicast groups for that link:

  • Solicited-node multicast group FF02:0:0:0:0:1:FF00::/104 for each unicast address assigned to the interface
  • Solicited-node for subnet anycast address for each unicast assigned address
  • Solicited-node for anycast address FF02:0:0:0:0:1:FF00::0000
  • All-nodes link-local multicast group FF02::1
  • All-routers link-local multicast group FF02::2

The neighbor discovery feature sends messages to these multicast groups. For more information, refer to IPv6 Neighbor Discovery Configuration.
