Hi experts,
I am using DMVPN before but I never studied it (run debug, wireshark, etc). Now I am going into the details. I started with a very simple topolgy using DMVPN phase 1 configuration without IPSec. My first question is about the NHRP network-ID. Apparently without it the NHRP process doesn't start. However the configured ID is not in the NHRP registration request or reply messages that I captured. In addition, spoke still registers with hub even with the wrong ID. Any ideas why? What is the purpose of the network ID?
Thanks,
Difan
