Hi Authors, Stephane,
In the last meeting [1], Stephane mentioned that the PCE is unaware of
the PCC's capability to push ELI/EL pairs and thus questioned the
usability of your I-D. He mentioned that existing information in
IGP/BGP-LS i.e. MSD, ELC, ERLD does not tell the PCC's capability to
push ELI/EL pairs.
The current draft has a single bit ELP -
A PCC sets this flag to 1 to
indicate that it supports the capability of inserting multiple ELI/EL
pairs and and supports the results of SR path with ELP from PCE.
I want to confirm if this bit and BMI-MSD enough? If not, what else?
It would be good if this can be discussed here or during the meeting.
Thanks!
Dhruv
