Routing

Routing can be used on the controller to support the VNS definitions. Through the user interface you can configure routing on the controller to use one of the following routing techniques:

• Static routes — Use static routes to set the default route of a controller so that legitimate wireless device traffic can be forwarded to the default gateway.
• Open Shortest Path First (OSPF, version 2) (RFC2328) — Use OSPF to allow the controller to participate in dynamic route selection. OSPF is a protocol designed for medium and large IP networks with the ability to segment routes into different areas by routing information summarization and propagation. Static Route definition and OSPF dynamic learning can be combined, and the precedence of a static route definition over dynamic rules can be configured by selecting or clearing the Override dynamic routes option checkbox.
• Next-hop routing — Use next-hop routing to specify a unique gateway to which traffic on a VNS is forwarded. Defining a next-hop for a VNS forces all the traffic in the VNS to be forwarded to the indicated network device, bypassing any routing definitions of the controller's route table.
