As Adrian pointed out:"A PCE may serve more than one domain." , and I am not
sure whether there are multiple PCEes may serve one domain(for HA or load
balance reason). If my assumption is reasonable, I am afriad just using the IRO
is not the best idea. Becasue, just based on the IRO, for a specific PCE, how
does it accurately know which domain(s) it should serve?
For example:there are three domains(d1,d2,d3) and three PCEs(PCE1,PCE2,PCE3),
PCE1 serves d1, PCE2 could serve d2 and d3, and PCE3 also could serve d2 and
d3, for such condition, how does BRPC work?
