Hi Gyan,
Thanks for your comments! This is a good question.
From my understanding, RFC8662 did not describe the ERLD computation is
required but specifuies that the ingress " should try to insert the minimum
number of such pairs".
Also as suggested by Andrew, the explaination will be added in section 3 as the
following shown.
"As described in [RFC8662], the ELRD value is an important consideration when
inserting ELI/EL and the minimum ELRD must be evaluated for each node along a
computed path. This necessary step adds additional complexity in the ELI/EL
insertion process and it may not be feasible for an ingress router to compute
the appropriate ERLD for each node in the path, since a SR-MPLS path may
contain segments the ingress router can resolve such as inter-domain scenarios."
It will be updated in the next version. Hope that could address your concern.
Thanks!
Best Regards,
Quan

Subject: Re: [Pce] WG Adoption of draft-peng-pce-entropy-label-position-10
I reviewed the draft and support WG adoption.
I believe this ELP PCE capability extension maybe helpful in determining the
position to place the ELI. EL label. According to RFC 8662 a {ELI,EL} label
must be placed after every SID in the sid list based on the ERLD. I maybe a
good idea to explain why computing the ERLD would add complexity in the ELI/EL
insertion process and why a new mechanism using the ELP is necessary. Also why
the ERLD computation is not required as described in RFC 8662.
Thanks
