RE: ISIS Hello Packet Problem posted 11/21/2003

Hi,

This is because R1 is your Designated IS for the broadcast network. The
DIS will send the hello messages more often, to about 1/3 of the
configured value. This is normal behavior according to the specs.

Cheers,

Subject: ISIS Hello Packet Problem

Guys,  have rtr1---------rtr2

rtr1 is sending isis hello packets every 5 seconds even though I set the
isis hello-interval to 15 seconds.  Router 2 seems to be working
correctly.
I have tried this on two different platforms now,  4700 running
enterprise
on code 12.2x and 2500s runnign 12.0xx

Anyone have any ideas on this please?


Many thx
