Segment routing statistics

The traffic statistics in a segment routing (SR) network can be recorded in an OpenConfig compliant format for Layer 3 interfaces. The statistics is recorded for the Source Packet Routing in Networking (SPRING) traffic only, excluding RSVP and LDP-signaled traffic, and the family MPLS statistics per interface is accounted for separately. The SR statistics also includes SPRING traffic statistics per link aggregation group (LAG) member, and per service identifier (SID). To enable recording of SR statistics, include the sensor-based-stats (per-interface-per-member-link <ingress | egress> | per-sid ingress statement at the [edit protocol isis source-packet-routing] hierarchy level.
