IPv6 routing
OS10 supports IPv6 routing and addressing, including the Neighbor Discovery Protocol (NDP), stateless IPv6 address autoconguration,
and stateful IPv6 address conguration. Congure IPv6 routing for IP hosts to communicate with one another in the same network, or in
dierent networks.
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 autoconguration 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 congured IPv6 addresses do not take eect. The IPv6
addresses take eect again when you re-enable IPv6.
If you disable IPv6 and congure 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.
