Can someone please tell me what is the interface ge-2/1/0.0 IS-IS level after we have applied this config?

Does Juniper takes both commands?

  • level 2 disable at the interface level
  • level 1 disable at the protocol level

Or just one of them?

protocols { 
        isis {
                level 1 { 
                interface ge-2/1/0.0 { 
                                        level 2 { 

                interface ge-2/2/0.0;
                interface lo0.0;

From my understanding I believe that the interface ge-2/1/0.0 will have both level 1 and level 2 disabled, but I am not sure.

Thank you

It seems that I was correct.

The interface ge-2/1/0.0 will have both level 1 and level 2 disabled.

I have just seen this question on the Junos Genius APP for Android.

  • I just tried configuring this on a pair of srx240's running Junos 12.1X44 both level one and two are disabled. Not what I'd expected, but it is correct – user13686 Feb 2 '15 at 20:21
