Hi, Peter: The definition of FAPM for IS-IS and OSPF doesn’t prevent from it is used for the intra-area prefixes. If we advertise the different loopback addresses via the FAPM, associate them to different Flex-Algo and related metrics, and does not allocate the MPLS SID, we can achieve the IP-Flex effect then. So, what’s the additional value of the IP-Flexalgo draft then?
