Re: Slightly OT: MPLS-FRR with Dynamips - not quite working as

Bryan,

In a real network I would expect to loose traffic in the order of
milliseconds but not 7-10 seconds as I have observed with Dynampis. My only
explanation so far is because I am running it on Dynampis and whilst it
simulates steady state behaviour fairly ok, probably can't cope with fast
changes that well.

Thanks
Elias
