Hi,
It's fine to use the neighbour command and there's lots of reasons that you
may want to. eg. to not announce networks to pc's that may be running RIP
listeners etc.
If you want to specify the neighbour command AND disable network broadcasts,
then use inconjunction with the "passive-interface" command:
> !
> router rip
> version 1
> passive-interface default
> network 172.16.0.0
> neighbor 172.16.200.20
> !
>
regards
Adam
