protocol-centric configuration. This may be changed in future. The isis configuration is applied directly within the appropriate
routing-instance where ISIS is activated.
In a protocol-centric configuration, the isis configuration is
applied within the standard-routing-instance and the instance list
helps to reference the routing-instance where ISIS is activated.
In a VRF-centric configuration, the isis configuration is applied
directly within the appropriate routing-instance where ISIS is
activated. In this case, the instance list will contain a single
element.
The ISIS configuration container is divided in: The ISIS configuration container is divided in:

5.1. Segment Routing activation
Activation of segment-routing IS-IS is done by setting the "enabled"
leaf to true. This triggers advertisement of segment-routing
extensions based on the configuration parameters that have been setup
using the base segment routing module.
5.2. Advertising mapping server policy
The base segment routing module defines mapping server policies. By
default, IS-IS will not advertise nor receive any mapping server
entry. The IS-IS segment-routing module permits to advertise one or
multiple mapping server policies through the "bindings/advertise/
