Hi Kireeti,

Just as a data point for comparison, the drafts in PCE WG were discussed in
the past. As part of use of PCE as a central controller PCECC (RFC 8283)
work items -

https://tools.ietf.org/html/draft-zhao-pce-pcep-extension-pce-controller-sr-05
https://tools.ietf.org/html/draft-dhody-pce-pcep-extension-pce-controller-srv6-01

The focus was on the controller to instruct the node with the SID
allocations when the controller learns about the existence of node and the
PCEP session is in place. We could also evaluate a request/reply from the
node as well if that approach is required.

Thanks!
Dhruv

point at hand is whether global SIDs should be managed "manually" (or by
NMS or equivalent) (i.e., static), or by a protocol (say DHCP) (i.e.,
dynamic).  You say the former ... thanks for the feedback.
