configuration management by a network administrator.
For large networks using OSPF with segmented OSPF areas, the OSPF area
(network group) for the Node/Terminal must be enabled along with entry of the
OSPF area number.
Dynamic routing must be used in 9500 MXC ring-network configurations.
Refer to 9500 MXC Address and Routing Options on page 10-2.
Interfacing OSPF to RIP
Where an OSPF-routed network is interfaced to a RIP-routed network, OSPF and
RIP must only be enabled on the interfacing router (9500 MXC terminal).
• If both OSPF and RIP are enabled on multiple 9500 MXC terminals in a
network, routes installed by one protocol are propagated by the other, resulting
in a proliferation of conflicting routes.
At the interfacing 9500 MXC terminal:
• Simultaneous RIP and OSPF is only enabled on the Ethernet interface.
• The radio link interfaces are set for OSPF or RIP - set to match the dynamic
routing option selected for the 9500 MXC network.
• This partitioning of routing selection is enabled in the Interface Addressing
screen.
9500 MXC Address and Routing Options
At the outset, a decision must be made to use single or interface IP addressing,
and static or dynamic routing. The screen-based configuration options are:
1. Single IP addressing and static routing:
• Use of a single IP address and subnet mask. This specifies the Ethernet port
address, and all other interfaces (links, V.24) assume this address.
• Requires manual configuration and maintenance of the routing table for all
devices within the network.
2. Single IP addressing with a combination of static routing and routing via
default gateways:
• Use of a single IP address and subnet mask (as for 1).
Within a 9500 MXC network that is using dynamic routing, select OSPF or RIP;
never both.
Where a 9500 MXC network must interface with a network that is using a different
dynamic routing protocol, only select both (OSPF and RIP) on the Ethernet
interface.
