This article describes how to change IS-IS metric style.

Scope FortiGate.
Solution

By default, the IS-IS metric style of FortiGate is narrow.

 

To change the IS-IS metric style, use the following commands.

 

# config router isis

     set metric-style <narrow | wide | transition | narrow-transition | narrow-transition-l1 | narrow-transition-l2 | wide-l1 or wide-l2 | wide-transition | wide-transition-l1 | wide-transition-l2 | transition-l1 | transition-l2>

  end

 

To use both narrow and wide, configure the metric-style to transition.

 

This is useful if FortiGate or the neighbor is unable to receive and advertised routes via IS-IS due to different IS-IS metric style. Both devices should have the same ISIS metric style so the routes will be learned via IS-IS successfully.
