Hi Laz, Please explain the commands by taking example of IPs we used in n/w topology for DMVPN. 1. ip nhrp map 172.16.123.1 192.168.123.1 2. ip nhrp map multicast 192.168.123.1 3)ip nhrp nhs 172.16.123.1 ( why are we using tunnel address here, it should be public ip) 3. diff b/w ip nhrp map multicast dynamic and ip nhrp map multicast 192.168.123.1 4. ip nhrp mode multipoint command instead of tunnel destination address. we know tunnel destination command is being used to specify destination address but multipoint mean it can be both source and destination ip. so how can we replace tunnel destination command by ip nhrp mode multipoint command? --- _[View the full topic](https://forum.networklessons.com/t/dmvpn-phase-2-basic-configuration/1306)._
