Many Cisco DMVPN (Dynamic Multipoint VPN)documents refer to NHRP (Next Hop Resolution Protocol) as the routing protocol to be used with dynamic IP addresses on spoke routers.
If I am using static assigned IP addresses on the spoke WAN facing interfaces, do I need to configure NHRP?
When configuring DMVPN, is NHRP automatically configured or is this a seperate configuration I must manually setup?
Does anyone have a current link to a Cisco NHRP document?
If you are doing DMVPN phase 3, you still need NHRP. The reason is you are not going to build static tunnels, and you still want spoke to spoke traffic to use your NMBA tunnel when there is traffic need to go from spoke to spoke. Where NHRP will be needed to help resolve spoke's physical interface IP address.
