Site-to-Site VPN Tunnel Down

[mosrahma]

Hi,

        I am trying to configure Site-to-Site VPN Tunnel using GNS3 for learning purpose for own sake, but always showing Session Status: Down. I got help from website and book, and followed all procedures, but still I could not make it work. I attached my configuration. Any kind of help will be appreciated.

Thanks,

Mostafa

Hi Srikanth,

Hi Mohammad,

Config looks perfect.

As i could see you not generated any VPN traffic.

Kindly generate Crypto ACL traffic form one of the two routers of R1 or R3.

Example:

R1#ping 172.16.10.1 source 10.10.10.1

or

R3# Ping 10.10.10.1 source 172.16.10.1

and provide the below output.

# sh crypto isakmp sa

# sh crypto ipsec sa

Regards,

Srikanth

In my case Mr Srikanth's answer did the magic. Its working perfectly fine. I created ,many scenarios but was not able to find the reason for down state.
