Configuring OSPF routing in the MAX
This section shows how to add a MAX to your OSPF network. It assumes that you know how
to configure the MAX with an appropriate IP address, (as described in Chapter 9, “Configuring
IP Routing.”)
The procedures in this section are examples based on Figure 8-6. To apply one or more of the
procedures to your network, enter the appropriate settings instead of the ones shown.
Figure 8-6. Example of an OSPF setup
In Figure 8-6, all OSPF routers are in the same area (the backbone area), so the units all form
adjacencies and synchronize their databases together.
Note: All OSPF routers in Figure 8-6 have RIP turned off. OSPF can learn routes from RIP
without the added overhead of running RIP.
Configuring OSPF on the Ethernet interface
The MAX Ethernet interface in Figure 8-6 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) on
one of the existing OSPF routers, and add MAX-1 to that area. You could then assign the same
area number (0.0.0.1) to all OSPF routers reached through the MAX across a WAN link.
After you configure MAX-1 as an IP host on that interface, you can configure it, in the
Ethernet profile, as an OSPF router in the backbone area. To configure MAX-1 as an OSPF
router on Ethernet, you need to make sure that the MAX is configured as an IP host and then
configure OSPF features.
