Application-specific link attribute in OSPFv2 for segment routing traffic engineering

You can advertise different te-attributes such as te-metric, delay-metric, or admin-groups for RSVP and flexible algorithms on the same link. This is done using flexible algorithm specific application-specific link attribute as defined in RFC 8920. To configure flexible algorithm application-specific te-attribute, include the application-specific statement at the [edit protocols ospf area interface] hierarchy level and the strict-asla-based-flex-algorithm statement at the [edit protocols ospf source-packet-routing] hierarchy level.
