Source Packet Routing in Networking (SPRING) or Segment Routing

  • Support for SRv6 SID in BGP export policy (MX Series)—Starting in Junos OS Release 23.1R1, you can list multiple Segment Routing for IPv6 (SRv6) segment identifiers (SIDs) for different services under a single routing instance or under a default instance in a BGP export policy. In earlier Junos OS releases, BGP allows only one SRv6 SID, which is the default SID per routing instance or under a default instance. This feature enables BGP to steer the traffic for each service (per service prefix) based on the best effort or Flexible Algorithm (flex algo) tunnel.
