help connecting vlans with 3 routers

[NinjaTurtle2021]

hi I tried so many things like router rip, ip route etc but I cannot connect my vlans altogether 

it seems only vlans 10,20,30,40,50 communicate but not 60 70 80

my architecture looks like this

SW1 (with vlans 10,20) ---- R1 ---- SW3 (with vlans 40,50) ---- R2 ---- R3 ---- SW4(with vlans 60,70,80)

  |

  |

 SW2 (with vlan 30)

can someone please help me

Hello,

post the running configuration of switch 4...

[Richard Burts]

You give a brief description of the topology, which vlans communicate and which do not, and a diagram. But there is no detail of what you have configured and no other information to help us identify the issue. As a start can you post the output of show ip route from SW4, R3, R2, and SW3. Also please give us the IP subnet associated with each one of the vlans.

I'd like to give you my .pkt file to show you the configuration but it seems I cannot attach it to my reply.

Hello,

you need to zip the .pkt file, then you can attach and upload it...

Hello,

basically, you had the wrong IP addresses on some of the interfaces connecting the routers to each other. You also had all subinterfaces for all Vlans configured on both routers, Router0 and Router2. Find attached the revised version. I have saved this in PT version 7.3.0, if you cannot open it, below are the router configs:
