Re: [Bier] Call for adoption: draft-wijnandsxu-bier-non-mpls-bift-encoding-01

[Toerless Eckert <[e-mail]>]

Eric, *

Q1: Is there any text you could point me to that would give
me an idea how a non bsl-sd-si encoding of the bift-id would
be beneficial (non-mpls of course) ?

Q2: What would be the harm of deploying software (non-mpls)
that would only support this bift-id encoding ? Specific example
welcome.

Thanks
