Segment Routing support on ACX2200

    hi Experts. 
    I am running 19.4R3 version on ACX220 . Any idea if Segment Routing support is available on that platform in the release 19.4R3 . If not, from which version is it going to be or already available.

    The feature is available on the acx2200 from 17.4.  You can configure basic pcep client support and both standard and spring controller.  But the label depth on the broadcom chips here is only 3 or 4.

    Tested IS-IS SPRING and it worked fine on ACX2200 platform. However, TI-LFA caused major problems. I suspected it could have been due to more than 3 labels (was using BGP-LU for seamless MPLS in the lab and configured L3VPN - in some scenarios would have had a VPN label, BGP-LU label, SR transport label, SR LFA label). Supposedly not only is TI-LFA not supported, but also not SR on ACX2200.
