I was more considering the case that the information is simply not propagated into the “downstream” area. There is no clear requirement to me that we need propagate capabilities and/or prefix SIDs for non-endpoint nodes across area boundaries, and hence we may not have visibility of each mid-point on the path. r. _______________________________________________ spring mailing list spring@ietf.org https://www.ietf.org/mailman/listinfo/spring
