DMVPN Phase 3 Basic Configuration


(Vitaly K) #22

Hello Rene,
I run 15.2(4)S5 on 7200. Is it possible to implement P3 if ip nhrp redirect failed ?

% NHRP-WARNING: 'ip nhrp redirect' failed to initialise

I looked up IOS features and Phase 3 seems supported.

thanks

Hello Vitaly

I was looking at the Cisco Feature Navigator and I was unable to find the 15.2(4)S5 IOS software release you mention:


Can you verify the release? Also, once that’s verified, you can use the Cisco Feature Navigator to verify that Phase 3 is supported. Let us know what you find!

Looking further into it I see that others are having similar problems when attempting to implement a similar lab using GNS3. It can be buggy, so it may be due to GNS3 and not the IOS version itself. Can you attempt it on another platform to verify?

I hope this has been helpful!

Laz

Thanks

I use real routers not GNS3, 7200, 2811,1841, 2921

P3 DMVPN cant be established. I will try 2921 as a hub.

The P2 config for IPSEC DMVPN (the lessons) does kill my tunnel comms. As soon as I remove IPSEC config statement from the tunnel interface it could have been reestablished with the two spokes I have.
the IPSEC wrapper breaks the membership
