Default metric
Load isis.cfg
Configure all routers so that the default metric is 100
Answer
To use a default metric of 100, we must use wide metrics. First we enable wide metrics everywhere. Then we set the default metric to 100.
Verification
Inspect the ISIS topology and see that the default metric has gone from 10 to 100:
The metric command under the ISIS router process dictates the default metric for all interfaces. Alternatively, you can manually configure the metric under each interface individually. (Or use an apply-group to apply the metric to all Gigabit.* interfaces).
