How do i understand what kind of DMVPN phase I am using?
I am following the configuration mentioned in http://www.cisco.com/en/US/tech/tk583/tk372/technologies_configuration_example09186a008014bcd7.shtml
I see spoke-spoke traffic directly going and see spoke-spoke IPSec tunnels setup. But I havenot used " ip nhrp redirect" and "ip nhrp shortcut". So how do I confirm if this is phase2 or 3. and what will be the difference between phase 2 and 3. I understand spoke-spoke is possible only in 2 and 3. but whats the difference?
Is there any command to check what phase I am using? The ios is 12.4(25d) on all routers.
If you have spoke to spoke tunnels being formed, you are not using phase 1, and are using at least phase 2 or higher.
Because you are not using the redirect or shortcut commands, you are not using phase 3.
In short, you are implementing DMVPN phase 2.
Good link Paul and thank you for the clarification Keith.
I ll try to test phase 3.
