routing two LANs

AlexTottman2015

Level 1

Hi everyone,

 

I can't seem to send packets across my network. I have WAN set up and traffic within each LAN works but can't seem to send anything across the routers. I have configured static routing and have sub interfaces set up to handle the vlans....

 

Can anyone advise what I might be doing wrong? I have attached the file for reference.

 

Thank you :-)

Hello, 

 

the multilayer switches are layer 3 switches, which effectively makes them routers. That means you need a layer 3 connection (FastEthernet0/24 to GigabitEthernet0/0), and you cannot trunk all VLANs through that single layer 3 link anymore.

I have revised your topology. I also removed all static routes and RIP, and replaced it with OSPF.

Hello,

Yours L3 devices, doesn`t have a route between their routers. I suggest you to include them in ospf process or use a default route for it.

Hi @AlexTottman2015 ,

 

As option B:

 

In router0:

-Remove all subinterfaces, except one (the g0/0.10, for example).
This subinterface will communicate with the L3 switch

-Remove the static route
-Eliminates protocol  ospf 10

-In the RIP protocol, leave only the 172.16.0.0 enabled

 

In router1:

-Remove all subinterfaces, except one (the g0/0.50, for example).
This subinterface will communicate with the L3 switch

-Remove the static route
-Eliminates protocol  ospf 10

-In the RIP protocol:

 

Router(config)#router rip

Router(config-router)#version 2

Router(config-router)#no auto-summary

Router(config-router)#network 192.16.50.0

 

After those changes, everything works ok.

 

Regards
