Re: GNS3 ntp master crashing my PC

Thanks Hammer! Are you running ntp master and ospf on the same router? I
have tried this on my server and my laptop in both Windows and Ubuntu. I
just downloaded c7200-adventerprisek9-mz.150-1.M3.bin thinking that going to
15.0 ios would help, but I get the same result every time.

The only thing they all have in common is that I run ntp master and have
ospf adjacencies. I have tried this on a very simple three router ospf
network. Those were the only two protocols running, but my ospf adjacencies
begin flapping as soon as I do ntp master on one of my routers.
