Configure IPv6 routing for IP hosts to communicate with one another in the same network, or in different networks. NOTE: OS10 does not support Routing Information Protocol Next Generation (RIPNG). Enable or disable IPv6 By default: • IPv6 forwarding is enabled on physical Ethernet interfaces, VLANs, and port groups. IPv6 forwarding is disabled only when you enable IPv6 address autoconfiguration on an interface and set it in host mode using the ipv6 address autoconfig command. • IPv6 forwarding is permanently disabled on the management Ethernet interface so that it remains in Host mode and does not operate as a router regardless of the ipv6 address autoconfig setting. If necessary, you can manually disable IPv6 processing on an interface so that the configured IPv6 addresses do not take effect. The IPv6 addresses take effect again when you re-enable IPv6. If you disable IPv6 and configure a Layer (L2) interface in Layer (L3) mode, IPv6 is not automatically re-enabled on the interface. You must manually re-enable it. A link-local address automatically generates when you re-enable IPv6 on an interface with the ipv6 enable command.

IPv6 routing

OS10 supports IPv6 routing and addressing, including the Neighbor Discovery Protocol (NDP), stateless IPv6 address autoconfiguration,

and stateful IPv6 address configuration. Configure IPv6 routing for IP hosts to communicate with one another in the same network, or in

different networks.

NOTE:

OS10 does not support Routing Information Protocol Next Generation (RIPNG).

Enable or disable IPv6

By default:

•

IPv6 forwarding is enabled on physical Ethernet interfaces, VLANs, and port groups. IPv6 forwarding is disabled only when you enable

IPv6 address autoconfiguration on an interface and set it in host mode using the

ipv6 address autoconfig

command.

•

IPv6 forwarding is permanently disabled on the management Ethernet interface so that it remains in Host mode and does not operate

as a router regardless of the

ipv6 address autoconfig

setting.

If necessary, you can manually disable IPv6 processing on an interface so that the configured IPv6 addresses do not take effect. The IPv6

addresses take effect again when you re-enable IPv6.

If you disable IPv6 and configure a Layer (L2) interface in Layer (L3) mode, IPv6 is not automatically re-enabled on the interface. You

must manually re-enable it.

A link-local address automatically generates when you re-enable IPv6 on an interface with the

ipv6 enable

command.
