This section describes the new features and enhancements to existing features in Juniper Extension Toolkit 18.2R1.

API

RIB service APIs—Starting in Junos OS Release 18.2R1, RIB APIs support the following route attributes:

  • preference

  • preference2

  • route tag

  • route tag2

  • color

  • color2

Preference—The route selection process uses route preference attributes to select the active route among the usable routes for a given destination. Preferences are optional unsigned 32-bit integer values (range 0 through 4,294,967,295). The lower the value, the better the route. Based on the preference array values, routes are sorted. Two preference values are supported. preferences[0] and preferences[1] represent preference and preference2 respectively in the command-line interface (CLI).

Route tag—Tags are optional unsigned 32-bit integer values (range 0 through 4,294,967,295) that can be associated with a route entry for use in policy matching. Route policies use tags to influence the route selection process. Two tags are supported. tags[0] and tags[1] represent tag and tag2 respectively in the CLI.

Color—Colors are optional unsigned 32-bit integer values (range 0 through 4,294,967,295) that can be associated with a route and can be used for policy matching. They are similar to route tags. Two colors are supported. colors[0] and colors[1] represent color and color2 respectively in the CLI.
