Description

Enable source packet routing in networking (SPRING) at all levels. SPRING, or segment routing, is a control-plane architecture that enables an ingress router to steer a packet through a specific set of nodes and links in the network without relying on the intermediate nodes in the network to determine the actual path it should take.

Note:

You can provision an IPv4 node segment index for a routing instance, not for a specific OSPF area. A node segment index is attached to the IPv4 router-id, if the router-ids are configured on the loopback interface. Otherwise, the lowest IP address on the loopback interface is chosen to attach the node segment identifier..

Options

index-range index range

Range of node segment indices allowed.

  • Default: 4096

  • Range: 32 through 4096

ipv4-index index

IPv4 node segment index.

  • Range: 0 through 4095

Required Privilege Level

routing—To view this statement in the configuration.

routing-control—To add this statement to the configuration.

Release Information

Statement introduced in Junos OS Release 16.2.
