Static Route not working on SVI

[karenmelkonyanstu]

Hello,

I've built very simple topology in GNS with Layer 3 Switches.
Static Routing is configured on

IOU1 and IOU3

IOU1[12.0.0.1]----[12.0.0.2] IOU2 [23.0.0.2]------[23.0.0.3] IOU3

If I configure ports as Layer3 ( no switchport) then I am able to ping from

IOU1 - > IOU3 23.0.0.3

BUT if I configure SVI on all switches , I am able to ping only

23.0.0.2 and not 23.0.0.3

Configuration is very simple - SVI configuration on switches , trunk on ports between switches and static routing on

IOU1 / IOU1

Why I'm not able to

ping 23.0.0.3?

Thanks in advance.
If anyone has different image - could you please try the same lab with the same config and let me know if it works for you?
I use

L2-ADVENTERPRISEK9-M-15.2-IRON-20151103.bin

JUST SMALL UPDATE(I've done the same lab in Packet Tracer and outcome is the same , so is it expected behavior?? if so then why and how to make it work?)

IOU1#show running-config interface vlan 12
interface Vlan12
ip address 12.0.0.1 255.255.255.0
end
IOU1#show running-config interface ethernet 0/0
interface Ethernet0/0
switchport trunk encapsulation dot1q
switchport mode trunk
end

IOU1#show ip route 23.0.0.3
Routing entry for 23.0.0.0/24
Known via "static", distance 1, metric 0
Routing Descriptor Blocks:
* 12.0.0.2
Route metric is 0, traffic share count is 1

IOU3#show ip route 12.0.0.1
Routing entry for 12.0.0.0/24

According to

IOU1

configuration

IOU1 e0/0

is configured as trunk...operates at L2...

If You want to see communication from

IOU1 to IOU3....

All routers

(IOU1, IOU2 and IOU3) E0/0

must be confiured as Routed port (L3)...

Here is the syntax for Routed port configuration:

IOU1(config)# Interface E0/0

IOU1(config-if)# ip address <ip address> <subnet mask>

IOU1(config-if)# no shudown

IOU1(config-if)# exit

I hope the above information is useful..

Thanks

Thanks for the response.
Yeah

Eth0/0

is configured as trunk but I span this

vlan to IOU2

and  I've also configured SVIs  so why I should not be able to

ping 23.0.0.3?

I am able to ping Between
1 and 2
2 and 3
I'm also able to ping as mentioned

23.0.0.2

from 1 but not

23.0.0.3

So basically SVIs act as Layer3 , but for some reasons I'm not able to

ping 23.0.0.3 of IOU3

Any other ideas?

If you add 

Ip routing 

In

l3sw and svi

not work then

It

gns3

limitations.

[karenmelkonyanstu]

Thanks for the response

ip routing

is configured. 

[Georg Pauwen]

Which IOS version in GNS does this limitation apply to ? My version works fine with

SVIs and ip routing

enabled.

[karenmelkonyanstu]

Thanks - I see you've updated your post but as I've mentioned in post if I configure as Routed ports it works fine.
The question is why it does not work when you have SVIs configure?

[Gopinath_Pigili]

Yes...mentioned...!!

Got it..!!

Hello,

I am using

vios_l2-ADVENTERPRISEK9-M), Version 15.2(4.0.55)E

it works fine. Make sure all Vlans (12 and 23) exist on all switches (I had to manually create them) and that the route on

IOU1

is pointing to

12.0.0.12

(as in your drawing, unless the drawing is wrong and the

next hop

need to be .2)

[karenmelkonyanstu]

VLAN 12

is configured on

IOU1

only.

VLAN12 and 23

is configured on

IOU2

VLAN 23 on IOU

Please keep in mind that I am able to ping from

 IOU2 both next hop IPs ( IOU1 and IOU3 )

I'm also able to ping from

IOU1 23.0.0.2 which is behind IOU2

but for some reasons I'm not able to

ping 23.0.0.3

I'm afraid it could be gns or image limitation.
Would you mind sharing your config and outputs please?

[Georg Pauwen]

Hello,

here are my configs. I am using an image where

ip routing

is enabled by default, so it doesn't show up in the running config.

I've used another image AND IT WORKS!
Thanks a lot everyone for help.

[karenmelkonyanstu]

I'm trying new image now......
Will keep you posted.
