I'm looking at an example of ISIS configuration that confuses
me. The requirement is to configure this router so that it
only exchanges L1 hellos with its neighbors. In the solution
they have the following, which I thought would suffice:

router isis
 net 49.0001.0001.0001.0001.00
 is-type level-1

Then, the part that confuses me is that they also add 'isis
circuit-type level-1' to the interface configs.

Why would that be necessary? Doesn't 'is-type level-1' force
this router to be a level one router on all interfaces?

Thanks,
John
