3.b.3 Dynamic Routing
Dynamic Routing, also called adaptive routing, describes the capability of a system, through which
routes are characterized by their destination, to alter the path that the route takes through the
system in response to a change in network conditions. The adaptation is intended to allow as
many routes as possible to remain valid (that is, have destinations that can be reached) in
response to the change.
This gateway supports dynamic routing protocol, such as RIPv1/RIPv2 (Routing Information
Protocol), OSPF (Open Shortest Path First), BGP (Border Gateway Protocol) for you to establish
routing table automatically. The feature of dynamic routing will be very useful when there are lots
of subnets in your network. Generally speaking, RIP is suitable for small network. OSPF is more
suitable for medium network. BGP is more used for big network infrastructure.
In the "Dynamic Routing" page, there are seven configuration windows for dynamic routing
feature. They are the "RIP Configuration" window, "OSPF Configuration" window, "OSPF Area List",
"OSPF Area Configuration", "BGP Configuration", "BGP Neighbor List" and "BGP Neighbor
Configuration" window. RIP, OSPF and BGP protocols can be configured individually.
The "RIP Configuration" window lets you choose which version of RIP protocol to be activated or
disable it. The "OSPF Configuration" window can let you activate the OSPF dynamic routing
protocol and specify its backbone subnet. Moreover, the "OSPF Area List" window lists all defined
areas in the OSPF network. Using the "Add" button to add and create one new OSPF area and the
"Edit" button to modify an existed one. Creation and modification can be done in the "OSPF Area
Configuration" window. However, the "BGP Configuration" window can let you activate the BGP
dynamic routing protocol and specify its self ID. The "BGP Neighbor List" window lists all defined
neighbors in the BGP network. By using the "Add" button to add and create one new BGP
neighbor and the "Edit" button to modify an existed one. You can do them in the "BGP Neighbor
Configuration" window.
