Few comments: 1) What makes you think that you cannot enforce the set of domains that you want to explore with BRPC using the IRO object specified in RFC5441? 2) If you have a mesh of domains and you try to compute the shortest inter-domain LSP according to some metric, you just cannot afford not to explore all of them (unless you make use of some super-TED comprising resources information on all domains). This is true whether you use of forward or backward path computation ? I am trying to understand your claim about why forward computation would solve these problems ? Thanks. JP.
