please check this link first : http://networklessons.com/rip/how-to-configure-rip-on-a-cisco-router/
and go to this part :
Router Hearts has these two interfaces and I used these network commands:
This works perfectly fine as you have seen. I also could have used just one network command:
If I would have used network 192.168.0.0 I would have had the same result. Both 192.168.12.0 /24 and 192.168.23.0 /24 fall within this range so RIP would have been activated on both interfaces and network 192.168.12.0 /24 and 192.168.23.0 /24 would have been advertised.
Even the following network command would work:
Network 0.0.0.0 basically means “enable RIP on all interfaces and advertise everything”. This is what we call the “shotgun approach”. I sometimes like to use it in labs when I quickly want to advertise all networks on my router.
can anyone help me why i wirte Hearts(config-router)#netw
ork 192.168.0.0 ???
i know to summarize the two network but the each network in different location ..
so who i know this network from fa0/0 or fa0/1 ????
and in this case if i ping for example from other router to 192.168.19.1 the packet will send to the router in the middle but it reply by echo request time out or destination unreachable ?
