For the specific case of PHP, it does not use a special BIFT-ID to signal PHP (especially when you consider the fact that we’re talking about “BIFT-ID”). The php draft says:

   A BIER incapable router, if acting as a multicast flow overlay
   router, MUST signal its BIER information as specified in [RFC8401<https://tools.ietf.org/html/rfc8401>] or
   [I-D.ietf-bier-ospf-bier-extensions] or [I-D.ietf-bier-idr-
   extensions], with a PHP sub-sub-TLV included in the BIER sub-TLV
   attached to the BIER incapable router's BIER prefix to request BIER
   PHP from other BFRs.  The sub-sub-TLV's type is TBD, and the length
   is 0.

   With MPLS encapsulation, the BIER incapable multicast flow overlay
   router MAY omit the BIER MPLS Encapsulation sub-sub-TLV, or MUST set
   the Label Range Base in BIER MPLS Encapsulation sub-sub-TLV to
   Implicit Null Label [RFC3032<https://tools.ietf.org/html/rfc3032>].

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

Hi  Senthil
I have one comment/question:
Section 1, is BIFT-id 1/2/3/4/5/6 been allowed in non-mpls case?

In MPLS encapsulation, value 0 to 15 is reserved and should not be allowed as BIER label I guess.

Thanks
Jingrong

Hi Folks,

Renamed draft-dhanaraj-bier-isis-non-mpls-extensions to  draft-dhanaraj-bier-lsr-ethernet-extensions

Major updates:
1) Added packet format details for OSPFv2 as well
2) Updated text to better explain the signalling of BIFT-id's
3) Renamed "non-mpls" to "ethernet" as this specific draft covers only "BIER over Ethernet".

Thanks,
Senthil
