If it is a Stub network, then i would prefer using something like EIGRP stub feature.

Though static would do the work but you would end up having routes from the hub everytime you create a VLAN on the spoke.

Totally agree with Narayan, and i'll say that it depends on the number of stub routers.

Moses has posted this same question on the WAN Routing and Switching forum where I have posted a response. In my response I took a different approach than Narayan and Mohammed. I believe that static routes are entirely adequate for an environment where there is a main router and some number of remote routers. And where the remote routers have only a single connection and it is to the main router. Dynamic routing protocols like EIGRP are effective when there are choices to make about network paths. Dynamic routing protocols can choose the best path and can react when a path fails and if there is an alternate path the routing protocol can send traffic over the alternate path.

But if there is only a single path available then the overhead of running a routing protocol must be compared to the convenience of not having to manually enter a static route for remote subnets.

Hi Rick,

Totally agree with you, my only concern was if the number of the stub routers is very high, then why should he enter a static route per each router, running RIP for example would have the minimum administrative overhead, anyway as you said its his call to choose whatever is convenient for him.
