Routing Configuration

Information
The VoiceFinder AP200 Gateway supports static routing protocol and dynamic
routing protocol. There are two kinds of dynamic routing protocol – Interior
Gateway Protocol (IGP) and Exterior Gateway Protocol (EGP.) IGP is used for
routing among the networks in the same manager's domain while EGP is for
routing among the network in different manager's domain. IGP includes RIP,
OSPF and IS-IS, and EGP includes BGP. The VoiceFinderAP200 Gateway supports
To use routing protocol in the VoiceFinderAP200 Gateway, upload the
routing process to the Gateway and designate the network that is going to
use the routing process.
It is not easy to select routing protocol for each Gateway. Please note the
following when selecting routing protocol.
Besides, the user needs to consider convergence time, reliability needs and
Internetwork delay characteristics.
The user can perform several kinds of routing protocol in the VoiceFinder
AP200 Gateway at the same time. If several kinds of routing protocol is used
in one Gateway, each kind of protocol may have its own path for the same
destination. In this case, routing protocol has priority to be displayed in the
routing table in order of static route, OSPF route, RIP route and default route.

only IGP – RIP and OSPF.
Network Size and Complexity – Normally, static routing is enough for
edge network. However, to perform dynamic routing in a small scale
network, use RIP. If the network is large or complex, use OSPF.
Whether Variable Length Subnet Mask (VLSM) Is Supported or Not – If
there are several subnet classes within the network, use routing protocol
that support VLSM such as static route, RIP v2 and OSPF.
