.. rubric:: HSR RedBox Support

The HSR RedBox feature extends standard HSR functionality by adding an interlink port
that bridges the HSR ring to an external network segment. This allows devices on the
external segment to communicate directly with HSR ring nodes as if they were part of
the same HSR Ring.

On AM64x, ICSSG can be used as an HSR Redbox. To enable this feature, the CPSW port
(``eth0``) must be connected to the external network to serve as the interlink port.

The existing :ref:`hsr_setup.sh script <hsr-setup-script>` can be used with small modification
