5. Configure IKE policies to specify the encryption algorithm, authentication algorithm, and keyexchange methods used by the router when attempting to establish a VPN connection.

6. Configure an IPsec transform set to specify the encryption and authentication algorithm used to protect the data in the VPN tunnel.

7. Configure a dynamic routing protocol to advertise the private networks behind the router to other routers in the DMVPN network. The available routing protocols are Open Shortest Path First (OSPF) and EIGRP. If no routing protocol is running, the routing process and network information must be entered, too.

To configure a DMVPN spoke, complete the following tasks in the DMVPN Wizard:

1. Specify the DMVPN network topology as a hub-and-spoke or fully meshed network.

2. Provide the hub physical and tunnel IP address.

3. Configure a GRE tunnel interface for the DMVPN connection.

4. Configure a preshared key or digital certificate.

5. Configure IKE policies to specify the encryption algorithm, authentication algorithm, and key exchange methods used by the router when attempting to establish a VPN connection.

6. Configure an IPsec transform set to specify the encryption and authentication algorithm used to protect the data in the VPN tunnel.

7. Configure a dynamic routing protocol to advertise the private networks behind the router to other routers in the DMVPN network. The available routing protocols are OSPF and EIGRP. If no routing protocol is running, the routing process and network information must be entered, too. Figure 23-30 displays the Select Routing Protocol screen.
