Statement introduced in Junos OS Release 16.1X65 for the PTX1000 routers.

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

Provisioning the IPv4 and IPv6 node segment index is allowed per routing-instance, and will NOT be allowed per IS-IS level. Node segment index is attached to the IPv4 and IPv6 router-id, if the router-ids are configured on the loopback interface. Else, lowest IP address on the loopback is chosen to attach the node-sid.

Options

index-range index range Range of node segment indices allowed.

Default: 4096

Range: 32 through 16384

ipv4-index index IPv4 node segment index.

Range: 0 through 199999

Note

Starting with Junos OS Release 17.2, the maximum index for IPv4 node segment index is 199999.

ipv6-index index IPv6 node segment index.

Range: 0 through 199999

Note
