Re: [ippm] [spring] Updates to draft-gandhi-spring-ioam-sr-mpls

Rakesh,

A couple of thoughts and questions.

- is it necessary to have three different ways to establish the
   IOAM Indicator Label?
- if it is necessary to use a Special Purpose Label, could you use
   a eSPL instead of a bSPL (for terminology see draft-andersson-mpls-
   spl-terminology)?
- will the label serving as as IOAM Indicator always be a the bottom
   of the stack and have the s-bit set?
- allocating SPL's is a decision that I would want the MPLS working
   group to take, this could be done in one of two ways, either we
   progress in the mpls wg or you split out the IANA allocation in a
   separate document and progress that in the mpls wg.
