Rip not send networks

Hi all,

I use Cisco packet tracer to make easy virtual labs.

Bassicaly i have a layer 3 switch conected to a router. The router have 3 networks and the switch have 3 networks. One of this networks its used to connect the switch and the router and is not propagated with the network command.

In the router-->router rip version 2 the 2 networks

In the l3 switch-->router rip version 2 the 2 networks.

I can ping the router and the switch in the respective interfaces of the network used to join the router and the switch.Why rip not propagatesthe other networks¿I have trued to  etablished passive interface in some interfaces, logycally  not in the interface where the router and the switch are connected.

In the networks i want to propagate i have  computers connected...I have reload the router and the l3 switch but rip not sends the routes...

Please help.

Re: Rip not send networks

Think the previous posters hit it on the head.  Here as the rtg table on R1

     10.0.0.0/24 is subnetted, 1 subnets
C       10.0.0.0 is directly connected, FastEthernet0/1
C    192.168.1.0/24 is directly connected, FastEthernet0/0.1
C    192.168.2.0/24 is directly connected, FastEthernet0/0.2

I checked out your conf and pkt file, I added the line to both RTR and SW of

router rip

network 10.0.0.0

Now the table shows:

Gateway of last resort is not set

     10.0.0.0/24 is subnetted, 1 subnets
C       10.0.0.0 is directly connected, FastEthernet0/1
C    192.168.1.0/24 is directly connected, FastEthernet0/0.1
C    192.168.2.0/24 is directly connected, FastEthernet0/0.2
R    192.168.3.0/24 [120/1] via 10.0.0.2, 00:00:01, FastEthernet0/1
R    192.168.4.0/24 [120/1] via 10.0.0.2, 00:00:01, FastEthernet0/1

Re: Rip not send networks

Hi,

Can you post the PKT file? To guide you through this issue, we definitely need to know your topology in detail.

It is important to note that the Packet Tracer only emulates the protocols but it does not really implement their logic. Do not try to infer too much about a protocol's internal operation by watching its behavior in Packet Tracer.

Best regards,

Peter

Re: Rip not send networks

Of course, this afternoon i post my pkt file.

have try to copy paste the running config but ive failed. Im not sure if i can copy from packet tracert.

I know packet tracer just emulate but i think its capable to send routes using rip, or not?

Thanks ¡¡¡

Re: Rip not send networks

  you would have to post the configs. The link between the switch and router must be on a common subnet and included in the network statements. Also make sure "ip classless" is in the config file.

Re: Rip not send networks

Thanks for the replyes. I have ipclassles. I add the pkt file ¡¡

Re: Rip not send networks

have you enabled routing on the L3 switch with the command ip routing ?

Re: Rip not send networks

Now it works...

1º) I have enable ip routing in the switch.

2º) i have included the existing network between the router and the switch in the network command for propagate him using rip...

Why its necesary include the network that links the switch and the router in the network command??? I dont want propagate him using rip and, the router and the switch knows this network because its directly connected.

Thanks all ¡¡¡¡

Re: Rip not send networks

the network command doesn't only tell which network to advertise but also that the interface must listen to rip updates and must send rip updates.

So if you don't put the connection between the router and the switch none of them will receive network advertisements from the other and none of them will send advertisements about networks to the other.

Re: Rip not send networks

Curiosly if i put the command "no ip routing" in the L3 switch. The L3 switch can route... It not works fine packet tracer...
