ipv6 nd autoconfig other-flag

Function

The ipv6 nd autoconfig other-flag command enables a user to use either NDRA or DHCPv6 to perform other configurations when NDRA is used to allocate IPv6 addresses.

Using the undo ipv6 nd autoconfig other-flag command, you can restore the default configuration.

By default, DHCPv6 is used to perform other configurations when NDRA is used to allocate IPv6 addresses.

This command is supported only on the NetEngine 8000 F1A.

Usage Guidelines

Usage Scenario

When NDRA is used to allocate IPv6 addresses, you need to run the ipv6 nd autoconfig other-flag command to select either NDRA or stateless DHCPv6 to perform other configurations.If the client supports the DHCPv6 mode, you can obtain the configuration information through the DHCPv6 Information-Request packet. If the access users in the same domain do not support the DHCPv6 mode, run the ipv6 nd autoconfig other-flag dhcpv6-enhance command to enable the DHCPv6-enhance function and enable the RA packet to carry the DNS attribute.

Prerequisites

For PPPoX and L2TPusers, the ipv6 nd autoconfig managed-address-flag command must not be run in the AAA domain view.

For IPoX users, the ipv6 nd autoconfig managed-address-flag command must not be run in the view of a specified interface.

Precautions

This command is supported only on the admin VS.

The ipv6 nd autoconfig other-flag dhcpv6 command or the undo ipv6 nd autoconfig other-flag command or the undo ipv6 nd autoconfig other-flag dhcpv6-enhance command restores the default configuration. This command is not contained in the configuration file.
