Source Packet Routing in Networking (SPRING) or Segment Routing

Support for Application Specific Link Attributes (ASLA) for flexible algorithms (ACX710, MX204, MX240, MX480, MX960, MX10003, MX 10008, MX10016, MX2008, MX2010, MX2020, PTX1000, PTX5000, PTX10002, PTX10008, PTX10016, VMX): IS-IS supports advertising different te-metric and admin-groups for RSVP and flexible algorithm on the same link using flexible-algorithm specific ASLA as defined in RFC 8919.
