Configuration On The Transit And Egress Routers - Juniper BGP - CONFIGURATION GUIDE V 11.1.X Configuration Manual

JUNOSe 11.1.x BGP and MPLS Configuration Guide
NOTE: For a topology-driven LSP, you have to configure and apply the classifier list
and policy list manually.

Configuration on the Transit and Egress Routers

When the tunnel is established, the JUNOSe software automatically creates an input
policy to match the EXP bits and map them to the traffic-class/color combinations
and attaches the policy to the incoming segment of the tunnel. The JUNOSe software
generates classifier list and policy list names, and creates the policy as if the following
commands were entered:
NOTE: You do not actually issue these commands; they represent the behavior
automatically performed by the router.
NOTE: For a topology-driven LSP, you must configure and apply the classifier list
and policy list manually.
