Hi, Xuerong and PCEers I have read the draft. It provides an alternate method that extends BRPC and PCEP protocol to get TE information of Inter-AS biderectional links. In my opinion, It is useful for the smooth upgrade of existing MPLS/GMPLS networks to support Inter-AS bidirectional path computation, because it need not any extension or modification to the IGP (such as OSPF and IS-IS) used in MPLS/GMPLS-enabled routers/switches. However, the method of IGP extension is also applicable and suitable for new network-equipments. So, I think there is no conflict between these two metods. The draft could be used in the scenario where the IGP extension of Inter-AS biderectional links can not be supported.
