2 Vlans on 2 switches and 1 router - help

[garbis1000]

Hi there. 

im trying to configure 2 vlans with the same name, one on each switch so they can "ping". but this doesn't work. I have tried with dot1q and trunk but I can't find any solution. Maybe it's because I'm new to this. If you could help me I would be very grateful. I leave the file and an image. the vlans are for the cameras.

Couple of questions to clarity here :

1. Router outside to ISP having same subnet as Lan ?

2. what is the Lan subnet mask ? and what gateway ?

Since the router in the between, you can not extend the Layer 2 VLAN via Router (unless you configure BVI Interface.)

Instead i would suggest to connect link between switches configure as Trunk in the interface config, that may  fix your issue, to have communication between

[garbis1000]

Hello, thanks for answering
No the router in the "isp" cluster is only there as a connection. It is to explain in an exhibition how the internet that reaches the company works. and regarding the configuration of the mask and all that is the following.

Router to SwitchIE: 192.168.1.2 255.255.255.192

Router to SwitchOA: 192.168.1.66 255.255.255.192

Ok so, when you refer to connecting the switches, do you mean without disconnecting them from the router?

[balaji.bandi]

If the switch acting as Layer 2, and router is configured as mentioned IP address and ip routing enabled both the side communication should work as expected.

One thing not clear in this diagram what is the IP address between Router to IP in the RED link ?

can you attached show run  information from router and both the switches to understand what configured.

[garbis1000]

If you see some interfaces with "voice vlan" it is because I programmed the phones with dhcp so that it automatically assigned the IPs and I excluded the rest of the IPs that I placed statically in the rest of the devices.

First, I would avoid using the VLAN1 default for any other purpose..

Try below config :

SwitchIE

create vlan 10 (this can be voice vlan)

config t
!
vlan 10
!
no interface Vlan1
!
interface Vlan10
ip address 192.168.1.62 255.255.255.192
no shutdown
!
ip default-gateway 192.168.1.2

use below example connecting to router port and other ports

interface FastEthernet0/X
switchport mode access
switchport access vlan 10
no shutdown
!

SwitchIE

create vlan 20

config t
!
vlan 20
!
no interface Vlan1
!
interface Vlan20
ip address 192.168.1.126 255.255.255.192
no shutdown
!
ip default-gateway 192.168.1.66

use the below example connecting to the router port and other ports

interface FastEthernet0/X
switchport mode access
switchport access vlan 20
no shutdown

Hello,

I have opened your file, and I have full connectivity. From which source IP to which destination IP can you not ping ?

Source IP: 192.168.1.5

Destination IP: 192.168.1.67

Success or Failure: S/F

[garbis1000]

Hey. 

Yes, you can ping any host. The problem is why I started the post because I want to create a vlan for the cameras and the server "vlan 10".

I can create a vlan on each switch with the same name but this does not guarantee that the SwitchIE cameras can ping the SwitchOA cameras. Actually that is my question.

What commands should I use?
