DMVPN issue in ISR4351

Level 1
Level 1

Hi, 

I tried to config DMVPN in ISR4351 as HUB and in c1900 as Spoke

But when I test connection from spoke to hub the connection failed.

The output of (show crypto isakmp sa )commend gave me active connection

IPv4 Crypto ISAKMP SA

    Dst                     src            state          conn-id status

10.10.10.5   10.10.10.1   QM_IDLE    1011 ACTIVE

 

 

But (show dmvpn)didn’t give me any result.

 

Legend: Attrb --> S - Static, D - Dynamic, I - Incomplete

        N - NATed, L - Local, X - No Socket

        T1 - Route Installed, T2 - Nexthop-override

        C - CTS Capable, I2 - Temporary

        # Ent --> Number of NHRP entries with same NBMA peer

        NHS Status: E --> Expecting Replies, R --> Responding, W --> Waiting

        UpDn Time --> Up or Down Time for a Tunnel

==========================================================================

 

What should I do?

any reply ???

What is the output 'sh cry ips sa'?

Enable debug crypto ikev1 sa, clear the tunnel and share the output of full tunnel negotiation. 

Also, keep debug ip nhrp enabled
