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.
as I said, we can not mix metrics for different data-planes.
So, what’s the additional value of the IP-Flexalgo draft then?
please read the draft. It defines the flex-algo for IP data plane.
thanks,
Peter

IS-IS Flexible Algorithm Prefix Metric Sub-TLV” and “OSPF Flexible Algorithm
Prefix Metric Sub-TLV” are defined for advertisement of algorithm specific
metric for inter-area inter-AS prefixes for SR-MPLS data-plane.
SR MPLS and IP are independent data-planes used for flex-algo. We can not mix
their metric.
