Configuring OSPF Routing
Configuring OSPF routing in the MultiVoice Gateway
Example of configuration adding the MultiVoice Gateway to an OSPF
network
This section describes how to add a MultiVoice Gateway to your OSPF network. It assumes
that you know how to configure the MultiVoice Gateway with an appropriate IP address as
described in Chapter 8, “Configuring IP Routing.” The procedures in this section are examples
based on Figure 9-7. To apply one or more of the procedures to your network, enter the
appropriate settings instead of the ones shown.
Figure 9-7. Example of an OSPF setup
In Figure 9-7, all OSPF routers are in the same area (the backbone area), so the units form
adjacencies and synchronize their databases together.
Note: All OSPF routers in Figure 9-7 have RIP turned off. OSPF can learn routes from RIP
without the added overhead of running RIP.
The MultiVoice Gateway’s Ethernet interface in the sample network diagram is in the OSPF
backbone area. Although there is no limitation stated in the RFC about the number of routers in
the backbone area, you should keep the number of routers relatively small, because changes
that occur in area zero are propagated throughout the AS.
Another way to configure the same units would be to create a second area (such as 0.0.0.1) in
one of the existing OSPF routers, and add the MultiVoice Gateway to that area. You could then
assign the same area number (0.0.0.1) to all OSPF routers reached through the MultiVoice
Gateway across a WAN link.
After you configure the MultiVoice Gateway as an IP host on that interface, you could
configure it as an OSPF router in the backbone area in the Ethernet profile. To configure the
MultiVoice Gateway as an OSPF router on Ethernet:
1 Open Ethernet > Mod Config > Ether Options, and make sure the MultiVoice Gateway is
configured as an IP host. For example:
Ethernet
Mod Config
Ether options...
IP Adrs=10.168.8.17/24
2nd Adrs=0.0.0.0
