2.5. Routing Configuration
VoiceFinder Gateway series support both of static routing and dynamic routing protocols.
Dynamic routing protocol can be divided by 2 different types: one is IGP(Interior Gateway
Protocol) which is used for routing between the networks within the same administrator’s
domain and the other is EGP(Exterior Gateway Protocol). RIP, OSPF, IS-IS are used for IGP
and BGP is used for BGP. The VoiceFinder Gateway supports RIP and OSPF.
To use routing protocol from VoiceFinder Gateway, you must put the routing process on the
gateway and specify the network to be used for.
Choosing the routing protocol to be used for the gateway is not that simple and consideration of
the following details are recommended
z Network Size and Complexity : Static Routing is commonly used for the Edge Network. If
you need to use Dynamic Routing, please use RIP for small network and use OSPF for
large network.
z If many subnet classes may exist together within a network, please use the routing
protocols which can support VLSM (Variable Length Subnet Mask) such as static route,
RIPv2, OSPF.
For others please consider Convergence Time, Reliability Needs, and Internetwork Delay
Characteristics
VoiceFinder can operate many routing protocols simultaneously. When a gateway uses many
routing protocols simultaneously, each protocol can be assigned with a calculated path for its
destination. The priority in routing table is Static route - OSPF Route - RIP Route - Default
Route order.
2.5.1. Static Routing Configuration
Static route is a specified route to send a packet to go on a path which designated by an
administrator. Static route can be used for the following 3 cases:
z A case where routing software fails to create a route towards a specific destination
