BGP-SR-TE rearchitecture

Junos OS provides support for controller-based BGP segment routing-traffic engineering (SR-TE) routes to be installed as source packet routing traffic-engineered (SPRING-TE) routes. BGP installs the SR-TE policy in the routing tables bgp.inetcolor.0 and bgp.inet6color.0, and these routes are subsequently installed in the routing tables inetcolor.0 or inet6color.0 by SPRING-TE. Junos OS controller-based BGP SR-TE routes are installed as BGP routes in the routing table. To maintain consistency and for easy maintenance, all SR-TE based routes appear as SPRING-TE routes irrespective of the source. You need to enable source-packet-routing at the [edit protocols] hierarchy level to see the routes installed in inetcolor.0 or inet6color.0. A new option detail is introduced under traceoptions (Protocols Spring-TE) to trace the detailed information.
