Dear authors and all,

Please consider the following comments.
1. Do you think it is ok to add one more segment type for the segment list to incorporate the segment for Layer 2 bundle members? Please refer to rfc8668.
2. For per flow steering to a policy, why do we limit the array index to 0 to 7?  I think this is implementation specific and the number of paths in an array depends on the application scenario. I am not sure whether or not 8 paths is enough for all scenarios.
3. For protection in section 9.1, it is better to add some text like "the local protection may not satisfy the SLA requirements or the path constrains for the policy" when an SR Policy is built on the basis of TI-LFA protected IGP segments.

Best Regards,
Zhenqiang Li
