Re: IS-IS issue over ethernet subinterface

Hi GS,

After adding the isis network point-to-point get the clns adj.

R1#sh clns neighbors

System Id Interface SNPA State Holdtime Type
Protocol
0000.0000.0002 Fa0/0.12 c20f.20fb.0000 Up 274 IS *ES-IS*
R1#

It is forming ES-IS instead of IS-IS

BUT still cannot get IS-IS to form adj.

R1#sh isis neighbors

System Id Type Interface IP Address State Holdtime Circuit Id
R1#

Regards

Dheven
