Source Packet Routing in Networking (SPRING) or Segment Routing

  • Support for SRv6 Flexible Algorithm in TED and BGP-LS (PTX 10004)—Starting in Junos OS Evolved Release 22.4R1, we support SRv6 Flexible Algorithms (flex algo) in the traffic engineering database (TED) and BGP Link State (BGP-LS). Flexible Algorithm allows routing protocols such as IS-IS and OSPF to compute paths over a network based on user-defined parameters such as calculation-type, metrics, and constraints. Note that we cannot define flexible algorithms specifically for either SR-MPLS or SRv6. If a node is participating in a specific flex algo, that flex algo would apply to both SR-MPLS and SRv6 nodes.
