IPv6 routing
OS10 supports IPv6 routing and addressing, including the Neighbor Discovery protocol, 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 front-panel 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 (ipv6 address autoconfig).
• 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 L2 interface in L3 mode, IPv6 is not automatically re-enabled on the interface. You must manually re-
enable it.
A link-local address is automatically generated when you re-enable IPv6 on an interface with the ipv6 enable command.
