RIP timer measurement in Packet Tracer

[BuGii]

I was checking RIP packet movement in SIM mode and noticed that update timers are not being sent precisely every 30s by each router. It is always a value of <24;30). Does anybody know why is that?

I would not really bother, It is a simulator, not a physical device

it has no real-time-clock that can interrupt exactly every 30 seconds.
With enough processing power the packet tracer host may do some tasks in parallel,
but it in a larger configuration it cannot really handle multiple router at the same time!
the simulator may take into account the processing time between cycles to send the packets.

Hello @BuGii ,

also in real routers the update timer is not exactly 30 seconds this is done also to avoid synchronization effects.

However, in a packet tracer emulation this update timer differentation can be amplified

Hope to help
