ipv6 enable

This command provides support for enabling IPv6 per data-router interface. When the IPv6 feature is included in the Software License Key, IPv6 is disabled per interface, by default. An IPv6-disabled interface will not have global IPv6 addresses enabled, nor will it have link-local addresses.

The show data ipv6 route command does not display routes of IPv6 interfaces that are disabled, but the interface is displayed by the show running config command. Configuration of IPv6 addresses can be done at any stage, but will only be active if IPv6 is enabled on the required interface.

Syntax

# ipv6 enable
# no ipv6 enable

Note

■

This command is applicable only to data-router functionality.

■

IPv6 support is available only if the installed Software License Key contains the IPv6 Feature Key. This flag does not replace the need of the Feature Key.

■

By default, all data interfaces begin with IPv6 disabled.
