PCE capabilities
Hi,
I wonder if it would be a good idea for a PCE to advertise among other
things the list of areaIDs/ AS numbers that it covers. Then a PCE can select
proper PCE(s) to work with, provided that it can identify (with the help of
routing) the area/AS of the path computation target. To go a step further a
PCE may separate areas/ASs that it covers directly (because it is within
their TE visibility) from those covered indirectly (because it learned about
other PCEs taking care of such areas/ASs).
