Hello,
IS-IS DIS sends hellos at 3.3 seconds, so does it means 3.3 seconds between DIS and all other routers as well as other routers also send hellos to DIS at the same seconds...
and IS-IS normall routers are exchanging hellos between them at 10 sec... is that correct?
so in short:
Hellos between DIS and ALl other is 3.3
Hellos between ALLother routers is 10 Seconds
regards
Devang
