VLANS with 2 routers and 2 switches

[Telim]

 Tracer 

I'm using Tracer and I'm doing a VLANS, sub interface but I cannot ping the computers, I can ping the computer to router and to switch but not btw computer. 

I need to know what I'm doing wrong please help. 

LEG A:  VLAN 10 and 20 are developed from 209.165.190.0/24.

LEB B: VLANs 30, 40 are developed from 192.168.100.0/24. 

Serial port addresses on router are from the 209 address.

Hi

The problem here is you have the gateway for the same VLANs on the both routers, so you should use HSRP or other FHRP to avoid this behavior, so your config could be:

(Assuming we are keeping the same default gateway for each network)

ROUTER 1

interface FastEthernet0/0.10

encapsulation dot1Q 10

ip address 209.165.10.253 255.255.255.0

standby 10 ip 209.165.10.2

standby 10 preempt

standby 10 priority 105

!

interface FastEthernet0/0.20

encapsulation dot1Q 20

ip address 209.165.20.253 255.255.255.0

standby 20 ip 209.165.20.4

standby 20 preempt

standby 20 priority 105

!

interface FastEthernet0/0.30

encapsulation dot1Q 30

ip address 192.168.30.253 255.255.255.0

standby 30 ip 192.168.30.2

standby 30 preempt

standby 30 priority 105

!

interface FastEthernet0/0.40

encapsulation dot1Q 40

ip address 192.168.40.253 255.255.255.0

standby 40 ip 192.168.40.4

standby 40 preempt

standby 40 priority 105

You can use a routing protocol to interconnect both routers or if you are already using VLANs through the switches it can work

router ospf 100

network 0.0.0.0 255.255.255.255 area 0

ROUTER 2

interface FastEthernet0/0.10

encapsulation dot1Q 10

ip address 209.165.10.254 255.255.255.0

standby 10 ip 209.165.10.2

standby 10 priority 100

!

interface FastEthernet0/0.20

encapsulation dot1Q 20

ip address 209.165.20.254 255.255.255.0

standby 20 ip 209.165.20.4

standby 20 priority 100

!

interface FastEthernet0/0.30

encapsulation dot1Q 30

ip address 192.168.30.254 255.255.255.0

standby 30 ip 192.168.30.2

standby 30 priority 100

!

interface FastEthernet0/0.40

encapsulation dot1Q 40

ip address 192.168.40.254 255.255.255.0

standby 40 ip 192.168.40.4

standby 40 priority 100

router ospf 100

network 0.0.0.0 255.255.255.255 area 0

* also you could verify the spanning tree protocol to be aligned with the primary HSRP router (higher priority)

Hope it is useful

:-)

I continue to have problems with it. I cannot ping them. 

I know I'm doing something wrong. 

[Georg Pauwen]

Hello,

I have made some changes to your config. All PCs can now ping each other. That said, as stated by the other posts, what is your requirement ?

[Telim]

What I try to accomplish is:

Create VLAN(s) 10,20,30,40

Configure sub-interfaces on Routers

Configure VLAN(s) on Switches

Pinging from end to end

With this ip address

Topology  2 Routers, 2 Switches and end devices.

LEG A:  VLAN 10 and 20 are developed from 209.165.190.0/24.

LEB B: VLANs 30, 40 are developed from 192.168.100.0/24. 

Serial port addresses on router are from the 209 address.

[paul driver]

Hello

I agree with @Julio E. Moisa

You have not only the same vlans on either leg but the same ip addressing, you need to redesign this topology but first can you explain what you trying to accomplish

[Telim]

What I try to accomplish is:

Serial port addresses on router are from the 209 address

Create VLAN(s) 10,20,30,40

Configure sub-interfaces on Routers

Configure VLAN(s) on Switches

With this ip address

LEG A:  VLAN 10 and 20 are developed from 209.165.190.0/24.

LEB B: VLANs 30, 40 are developed from 192.168.100.0/24. 

[Georg Pauwen]

Hello,

what do you mean by 'developed'...do you mean reachable ?

LEG A: VLAN 10 and 20 are developed from 209.165.190.0/24.

LEB B: VLANs 30, 40 are developed from 192.168.100.0/24.

[Telim]

Yes, like this is the addressing plan developed for accessing networking devices.

[Georg Pauwen]

Did you open the revised file I sent ? There should be full connectivity, I only took the IP addresses off the FastEthernet0/0 interfaces because I didn't know what they were for. Add them back and you should meet your requirements...

[Telim]

Yes, I did. It is not pinging from end to end
