Easy Cisco routing question

I am studying for my ccna and while practicing with my 2503's i was in the end unable to ping the hosts on either of the networks. so you know i have two 2503's connected via a DTE/DCE cable, i can ping from either of the routers any on the interfaces however i am unable to ping from the hosts the interfaces or from the routers the hosts. is there something i am missing here?

here are the configs

R1--------------- Current configuration : 1037 bytes ! version 12.1 no service single-slot-reload-enable service timestamps debug uptime service timestamps log uptime no service password-encryption ! hostname r1 ! logging rate-limit console 10 except errors enable secret 5 $1$/GLh$tiUUZ5NiVBCbfgQgT.R9J1 enable password password ! ip subnet-zero no ip finger ! cns event-service server ! ! ! ! ! interface Ethernet0 ip address 192.168.1.1 255.255.255.0 priority-group 1 ! interface Serial0 ip address 192.168.3.1 255.255.255.0 clockrate 4000000 dce-terminal-timing-enable ! interface Serial1 no ip address no ip mroute-cache shutdown no cdp enable ! interface BRI0 no ip address no ip mroute-cache shutdown no cdp enable ! router rip network 192.168.0.0 ! ip kerberos source-interface any ip classless ip route 0.0.0.0 0.0.0.0 192.168.3.2 ip route 192.168.2.0 255.255.255.0 192.168.3.2 no ip http server ! access-list 1 permit any ! snmp-server community public RO ! line con 0 exec-timeout 0 0 transport input none line aux 0 line vty 0 4 password password login ! end

Hi Danny, The routers' configurations seems fine. You've mentioned that the routers can ping each others interfaces, so it doesn't seem like a routing problem.

Is the default gateway configured correctly? Can the station ping its default gateway? Can the station ping the remote router?

Danny, You have configured three different ways of routing and you don't nned to do so. First thing, Your have misconfigured RIP. The RIP networks on router R1 should be: 192.168.1.0 and 192.168.3.0 The RIP networks on router R2 should be: 192.168.2.0 and 192.168.3.0

Second, Try to make the default route on R1 ip route 0.0.0.0 0.0.0.0 serial0 and on R2 ip route 0.0.0.0 0.0.0.0 serial0

Thrid, Try to make a single static route on R1: ip route 192.168.2.0 255.255.255.0 serial0 And on R2: ip route 192.168.1.0 255.255.255.0 serial0

Please notice that you only need one of the three points that I have mentioned, you don't need the whole thing. RIP, default route, or static route its your choice.

First, your Serial interfaces do not participate in RIP. You have to add any interface (basically IP Subnet of the Interface) into a routing protocol to send/receive route updates.

Second, just do "show ip route" to see if your router knows how to reach remote network. Default Gateways are good too, but you have to make sure they point to right direction.

Good luck,
