Can anyone point me to a resource to determine possible root causes of this error message:
%NHRP-3-PAKERROR: Received Error Indication code: loop detected(3),
are you config ip nhrp responder ?
No. We basically use NHRP in a DMVPN setup, 2 Cisco 1111 devices at the same site with tunnels sourced off Gig interfaces to the primary ISP
So your router C1111 is spoke, I think the Hub is config ip nhrp responder and since C1111 is spoke you must config same IP hub use as responder in ip nhrp nhs. check this point
can you post the full configs of the hub and the spoke routers ?
