Spoke Configuration
This window contains information that you can use to give a spoke router a
configuration that will be compatible with the DMVPN hub that you configured.
It lists the windows you need to complete, giving you data that you need to enter
in the window so that the spoke will be able to comm unicate with the hub.
It provides the following data that you need to input into the spoke configuration:
•The hub’s public IP address. This is the IP address of the hub interface that
supports the mGRE tunnel.
•The IP address of the hub’s mGRE tunnel.
•The subnet mask that all tunnel interfaces in the DMVPN must use.
•The advanced tunnel configuration information.
•The routing protocol to use, and any information associated with the protocol,
such as Autonomous System number (for EIGRP), and OSPF Process ID.
•The hash, encryption, DH group, and Authentication Type of the IKE policies
that the hub uses, so that compatible IKE policies can be configured on the
spoke.
•The ESP and Mode information of the transform sets that the hub uses. If
similar transform sets have not been configured on the spoke, they can be
configured using this information.
