Description: The value of vRtrIsisLevelPreference specifies the preference level to be used with internal routes at this IS-IS level. A route can be learned from different routing protocols supported in the system, in which case their costs are not comparable. In this case the preference value is used to decide which route to use.

The initial default internal preference value for IS-IS level 1 is 15. The initial default internal preference value for IS-IS level 2 is 18.

What is vRtrIsisLevelPreference?

The administrative preference (1-255) applied to internal routes learned at this IS-IS level, used the same way as vRtrIsisLevelExtPreference but for internal routes; the initial defaults are 15 for level 1 and 18 for level 2.
