Anyone can tell me what command i forgot to input to the router or
what command must be used with RIP v1 ??
I don't why, i can't ping from Network A to Network B

Network A ----- Router A ---(RIP v1)--- Router B -----Network B

you need to advertise the two connected networks on both routers. Like this:

**Assuming the Point-to-Point network is Network "C"**
routerA(config)# router rip
routerA(config-router)# network A (network address)
routerA(config-router)# network C (network address)
routerA(config-router)#exit

routerB(config)# router rip
routerB(config-router)# network B (network address)
routerB(config-router)# network C (network address)
routerB(config-router)# exit

Thats pretty much it. Remember that Rip v1 doesn't support CIDR/VLSM, so all of your networks must be contiguous. Hope that helps.
