Ping between VLAN's

[Marco_Cordero]

Hi, I have this issue where I'm trying to create multiple networks with a couple of routers on a stick. I've succesfully pinged between one side to the same side but not from one to another. Here's an image of the logical diagram.

S0 has Vlan 10, S1 has Vlan 20 and so on. I can ping from PC0 to PC1 but not from PC0 to PC2.

I already configured subinterfaces on the router but I don't know what to configure on the central portion of the diagram.

Hi @Marco_Cordero 

Try this

Router0

R(config)#ip route 192.168.0.96 255.255.255.224 se0/x/x <— must be the serial interface in use of this router

R(config)#ip route 192.168.0.128 255.255.255.224 se0/x/x <— must be the serial interface in use of this router

Router1

R(config)#ip route 192.168.0.0 255.255.255.224 se0/x/x <— must be the serial interface in use of this router

R(config)#ip route 192.168.0.32 255.255.255.224 se0/x/x <— must be the serial interface in use of this router

Well, that seem to work but I'm trying to configure subinterfaces and VLAN's, do I really need to define routes? I thought that between VLAN's one didn't need that, what's the explanation behind this?

Hi @Marco_Cordero 

Routers divide broadcast domains, so if you have more than one router, you must route, either with static routes or routing protocols.

I thought so, thnx.
