I am stuck in that that switch can't ping router and router can't ping switch. How to fix that ?

I tried so much variants but them didn't help me

Actually router must do static routing, that i am trying to do but that doesn't help me

I know that some config is awful here, actually on that connected switch but I am learning. Picture

enter image description here

  • please provide screen shot of your diagram. You can insert it here. – infra Jun 11 at 17:27
  • If you have doubt about your code which you configured, code sample also – infra Jun 11 at 17:30
  • @infra, done. code sample provided and picture also too – Awesome Man Jun 11 at 17:40
  • You've got two routers and three L3 switches in your diagram. Which ones can't ping each other and where are the links in between? Which ports connect to each other? – Zac67 Jun 11 at 18:18
  • @Zac67, Second router is redundant , i have tested one thing. that router what is connected need to be configured – Awesome Man Jun 11 at 18:59

I assume you want to connect switch interface FastEthernet0/1 to the router interface GigabitEthernet0/1 is that right?

If you want to route traffic from vlan 2-11 to the router you must:

  • delete interface Vlan12
  • configure the IP directly on the interface FastEthernet0/1

interface FastEthernet0/1 ip address 192.168.0.82 255.255.255.248

Now it should be possible to ping the switch from the router or vice versa

  • It is impossible to configure IP on any interface on L3 switch without Vlan – Awesome Man Jun 12 at 15:07

    @AwesomeMan, you clearly don't know how to configure an IP without a vlan, but it's quite simple (assuming the switch supports it). Go into interface config mode, type no switchport, and then configure your IP address – Mike Pennington Jun 13 at 11:47
  • @MikePennington, thanks! – Awesome Man Jun 13 at 11:56

You need to configure router-on-a-stick.

interface FastEthernet0/1
 switchport trunk allowed vlan 2-11
 switchport trunk encapsulation dot1q
 switchport mode trunk
 switchport nonegotiate

Router(config)# interface g0/0.20
Router(config-subif)# encapsulation dot1q 20
Router(config-subif)# ip add x.x.x.x x.x.x.x
Router(config-subif)# interface g0/0.30
Router(config-subif)# encapsulation dot1q 30
Router(config-subif)# ip add x.x.x.y x.x.x.x
....(add remanining vlan 4,5,6...)
Router(config)# interface g0/0
Router(config-if)# no shut
