IS-IS Hello Interval ?

Hi,

From Doyle and ref IS-IS,

"Hello’s are transmitted every 10 seconds"

Doyle fails to mention if this is for broadcast networks or point-to-point networks. I would have thought that this would be for broadcast networks and that point-to-point would be a longer time period.

Can anyone shed any light on this ?

Cheers,

Phil.

Re: IS-IS Hello Interval ?

The default hello interval for both point-to-point and broadcast is 10 seconds. However, for the DIS on the broadcast media, the default interval is 3.3 seconds.
