Hi,

these are larger, but important change and we would like the WG to review them. Changes are mostly OSPF specific, except the last item which is an editorial one.

The changes include:

1. introduction of the OSPFv2 Extended Inter-Area ASBR LSA, OSPFv2 Extended Inter-Area ASBR TLV and OSPF Flexible Algorithm ASBR Metric Sub-TLV. These are used to advertise the FA specific inter-area metric for the ASBRs, similar to what the FAPM does for prefixes. We clearly missed these originally.

2. introduction of the E-bit in the OSPF OSPF FAPM Sub-TLV to support the OSPF external metric types for FA. This was also missed originally.

3. related clarifications in "Multi-area and Multi-domain Considerations" section related to the above.

4. updated IANA sections as a result of (1) and (2).

5. clarification of the ASLA usage in presence of the L-bit - this has been requested by Tony. No functional change, just an editorial change really.


thanks,
Peter

Abstract:
    IGP protocols traditionally compute best paths over the network based
    on the IGP metric assigned to the links.  Many network deployments
    use RSVP-TE based or Segment Routing based Traffic Engineering to
    steer traffic over a path that is computed using different metrics or
    constraints than the shortest IGP path.  This document proposes a
    solution that allows IGPs themselves to compute constraint-based
    paths over the network.  This document also specifies a way of using
    Segment Routing (SR) Prefix-SIDs and SRv6 locators to steer packets
    along the constraint-based paths.
