  • 1.  Question on Segment Routing BGP Color Community Processing

     
    Posted 08-27-2023 08:56

    Hi.

    I'm testing the processing of received Segment Routing BGP Color communities, and I find that the segment-routing-te configuration, though mentioned in Juniper training documentation, doesn't really do anything. I remove it and nothing changes. So what's this knob for?

    protocols {

       bgp {

          group IBGP {

             type internal;

             local-address 192.168.100.7;

             family inet {

                segment-routing-te; <<<<<<<<<<<< What's this for?

                unicast {

                   extended-nexthop-color;

               }

           }

       }

    }

    Thanks,

    Deepak

    Hi,

    Only "extended-nexthop-color" is required for next hop resolution via "inetcolor.0".

    "segment-routing-te" is used for a different purpose. It allows BGP to be used as a transport protocol to carry SRTE policies.
