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.
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.
|
| ipv4-index index | IPv4 node segment index.
