ip rip v2-broadcast command - why do we need to use broadcast instead of multicast in RIP?

Hello,

why do we need to use broadcast instead of multicast in RIP?

 

As far as I know multicast is better than broadcast because only communicates with certain devices that are configured with RIP so what is the goal of using: ip rip v2-broadcast?

 

Thanks in advance.

 

Regards.

Hello,

 

most likely the broadcast is used for RIPv1 (which uses broadcast instead of multicast) compatibility...

Hello

Rip v1 -  can send updates either broadcast (  UDP 520-255.255.255.255) or unicast ( UDP520= dst ip xxx) or both
Ripv2 - can send updates either multicast ( UPD 224.0.0.9 or unicast  ( UDP520= dst ip xxx)  or both multicast / unicast

and lastly also broadcast (  UDP 520-255.255.255.255) via  ip rip v2-broadcast

 

ip rip v2-broadcast can be applied to a routers interface to send broadcast updates towards attached hosts or others rtrs that don't listen on mutlicast addresses

what could be the that kind of routers that cannot use multicast? Routers using RIPv1? so RIPv1 can communicate with RIPv2 by using the command that enables broadcast?
