3. Click Select next to Device Name, enter part or the entire name of the ingress device and click the
Query button. Devices matching this description appear in the Device Query List section of the
page. Select the ingress device, and then click OK.
4. Click Select next to Tunnel Name, enter part or the entire name of the tunnel that you want traffic
to be introduced to in the Tunnel Name field, and then click Query. Tunnels matching this
description appear in the Tunnel Info List section of the page. Select the tunnel you want, and then
click OK.
5. Select Static Routing, IGP Shortcut, or Forwarding Adjacency from the Traffic Access Type list,
depending on how your network was set up.
Static Routing—Static Routing is not really a routing protocol. Static Routing is the process of
manually entering routes into a routing table of a device via a configuration file that is loaded
when the routing device starts up. As an alternative, these routes can be entered by a network
administrator who configures the routes manually. Since these manually configured routes do not
change after they are configured, they are called static routes. Static Routing is the simplest form
of routing, but it is a manual process.
A static routed environment is best suited to a small, single-path, static network. A small network is
defined as 2 to 10 networks. Single-path means that there is only a single path for packets to travel
between any two endpoints on the network. Static means that the topology of the network does not
change over time. You only need to manually create a route that reaches the destination through
the tunnel interface.
Static Routing has disadvantages. If a router or link goes down, static routers do not sense the fault
or inform other routers of the fault. Therefore it is suitable for small networks where routers or
networks do not go down often enough to justify deploying a multipath topology and a routing
protocol. Besides, Static Routing does not handle failures or changes in networks well. For
example, if a new network is added or removed from the network, routes to the new network must
be manually added or removed. If a new router is added, it must be properly configured for the
routes of the network.
