General configuration steps

This section provides an overview of the general configuration steps for enabling IPv6 on a given VLAN Virtual Local Area Network. In computer networking, a single Layer 2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them through one or more routers; such a domain is referred to as a Virtual Local Area Network, Virtual LAN, or VLAN. by any one of several commands. The following steps provide a suggested progression for getting started.

Procedure

  1. If IPv6 DHCP service is available, enable IPv6 DHCP on the VLAN. If IPv6 is not already enabled on the VLAN, enabling DHCPv6 also enables IPv6 and automatically configures a link-local address using the EUI-64 format.

  2. If IPv6 DHCP service is not enabled on the VLAN, do either of the following:

    1. Enable IPv6 on the VLAN.

      Automatically configures a link-local address with an EUI-64 interface identifier.

    2. Statically configure a unicast IPv6 address on the VLAN.

      If you configure anything other than a link-local address, it enables IPv6 on the VLAN Virtual Local Area Network. In computer networking, a single Layer 2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them through one or more routers; such a domain is referred to as a Virtual Local Area Network, Virtual LAN, or VLAN. and the link-local address is automatically configured with an EUI-64 interface identifier

  3. If an IPv6 router is connected on the VLAN, then enable IPv6 address autoconfiguration to configure automatically a global unicast address with prefixes included in advertisements received from the router. The interface identifier used in addresses configured by this method will be the same as the interface identifier in the current link-local address.

  4. If needed, statically configure IPv6 unicast addressing on the VLAN interface as needed. Also includes statically replacing the automatically generated link-local address.
