Spokes can't ping each other in DVTI VPN setup

Level 1

Hello All,

Hope you all are doing good !

I need your support to fix following issue which i;m facing right now in my lab using DVTI configuration.

Note:- This all setup in GNS3.

Note:- All the routers are running Version 15.2(4)S1 .

Issue:- I can't reach any of the spokes interfaces from any of the other spokes while can ping every spokes from HUB itself also from every of the spokes can ping across HUB subnet .

Tried to ping and trace spoke R3 interface from spoke R2 :-

R2#ping 10.3.3.3 source 10.2.2.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.3.3.3, timeout is 2 seconds:
Packet sent with a source address of 10.2.2.2
.....
Success rate is 0 percent (0/5)

R2#traceroute 10.3.3.3 source 10.2.2.2
Type escape sequence to abort.
Tracing the route to 10.3.3.3
VRF info: (vrf in name/id, vrf out name/id)
1 1.1.1.1 44 msec 44 msec 48 msec
2 * * *
3 * * *

Treid ping from spoken R2 to HUB:-

R2#ping 10.1.1.1 source 10.2.2.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.1.1.1, timeout is 2 seconds:
Packet sent with a source address of 10.2.2.2
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 28/50/132 ms

If i see the config part it seems perfect also i tried to check tunnel status it's also seems up and active on all the spokes and HUB.

Also on top of this i'm running EIGRP and it's up and running (neighbour are up and exchanging routes ) perfectly as can see the routes on all the spokes and HUB.

I verified the configuration again and it seems perfect however would like to know your further views on this so herewith attaching my design and configuration .

Here is the imp output from HUB and spoke R2 and R3 + their running config

Your problem is split-horizon on the hub.  Turn it off and then you should be able to send traffic spoke to spoke.

interface Virtual-Template1 type tunnel

  no ip split-horizon

HI ,

I tried the same thing but no luck and as i confirmed earlier that i'm getting the routed on all the spokes but data traffic is not being pass through .

However i replaced the routers in the topology with ver (12.4) and applied the same config then it's working perfectly .

So i'm suspecting some thing wrong with that IOS .

Anyway thanks for your reply. 

Dear Samy,

I have same problem , please can you tell me which IOS you are using to solve this problem

Because I have the same problem with multiple configuration, using pre-shared key and certificates

Regards

Ali El Khatib

Hi Ali,

I have replaced my topology with IOS ver 12.4 and then it's working perfectly. 

Thanks.

Hello I did this too, and it worked but unfortunately it dosent support Ikev2, did you find a solution for the ikev2 ?

Thanks for your help

Hello Ali,

For ikev2 you can use ios ver 15.2(4)S1 it works perfectly until and unless you configure DVTI Flex VPN  .

Once you will configure DVTI flex VPN you will have the same issue like DVTI . 

Thanks.

Plrememberer to select a correct answer and rate helpful posts

Yes , I did lot of search no one has mentioned this issue and how to solve it, I don't know if it is bug because I have tried it also on UnetLab , I did the configuration and when it came to DVTI spokes couldn't ping to each other with IOS 15.4 or with Ikev2 configuration

Thanks for your help

Not applicable

Im having the same issue, running Version 15.2(4)S7 Flexvpn with DVTI. I just cant get the spokes to ping each other, icmp debug on the HUB does not give me any output either when I ping between spokes.

Hi Mate,

Did you find the right Ios image to implement flexvpn DVTI.
I tried to implement using c7200-adventerprisek9-mz.152-4.S4.image, spoke locations routes are learnt at all spoke locations.but not able to ping those spoke lan ip's.

trace drops at hub

do you have any solution to implement flexvpn dvti?
thanks,
Karthik

Finally I found the solution.

As Cisco says, Cisco 7200 doesn't support fully ikev2 configuration.

Nonetheless, you can configure flexVPN DVTI using tunnel mode gre ip
instead of tunnel mode ipsec ipv4 on GNS3.

I tested my topology using csr1000v (on GNS3 1.3.11) instead of Cisco 7200
and everything is ok.

When the tunnel are building on spokes, we can see:

NOTE Here I shut down fa0/0 on R1 and the tunnels point to R4 (Backup
FlexVPN Server).

Hello.

Using standard GNS3, ikev2 only works using 7200 series Routers.

But IKEv2 is not supported on this router (at least, this is what Cisco says).

Nevertheless, using GRE over IPSec this works fine (changing tunnel mode ipsec ipv4 by tunnel mode gre ip on Hub and spokes).

 

Bye, bye.

I was having the same issue with GNS3 lab here, studying for SIMOS exam and bumping my head against the wall because i double check everything within hub and all spokes like, 5 or 6 times. I changed the tunnel mode from ipsec to GRE and it worked perfecly. Is that a know bug? What a bummer...

Hello.

In a Hub and spoke topology using DVTI, disabling split horizon is not necessary in virtual template, because different virtual access  exist for every tunnel (two different virtual access if you have one hub and two spokes, three different virtual acceess for one hub and three spokes, ...). So when updates come from a tunnel to hub, they enter by one of the virtual access and leave from the rest of the virtual access.

Finally I found the solution.

As Cisco says, Cisco 7200 doesn't support fully ikev2 configuration.

Nonetheless, you can configure flexVPN DVTI using tunnel mode gre ip instead of tunnel mode ipsec ipv4 on GNS3.

I tested my topology using csr1000v (on GNS3 1.3.11) instead of Cisco 7200  and everything is ok.

 

When the tunnel are building on spokes, we can see:
