Hi Xiejingrong,

RFC8296 do not reserve any BIFT-id's (for non-mpls networks) to be used for
special purposes.

But yes, it might be a good idea to reserve a BIFT-id range to be used for
special purposes in non-MPLS networks.
One use case i can think of is PHP (use special values like Implicit NULL,
Explicit NULL label in MPLS) which could be applied to non-MPLS networks as
well like BIER over Ethernet.

BIER'ers, kindly shoot your opinion !

Thanks,
Senthil
