Routing
OSPF
Redistribute Routes Discovered by Other Methods
Many networks use more than one routing protocol. Routing protocols dis-
cover routes in different ways. They provide overlapping, but not identical,
services. For example, OSPF is an interior gateway protocol that cannot
discover external routes. You can run two protocols on your TMS zl Module
and redistribute routes from one protocol into the others.
You can also redistribute directly connected routes and static routes.
Redistributing RIP Routes. For some networks, you might need to use
several routing protocols. If you use both OSPF and RIP on the network, the
TMS zl Module can redistribute routes discovered by RIP into OSPF. To enable
the module to redistribute RIP routes, select the RIP check box in the Network
> Routing > OSPF window.
Redistributing Connected and Static Routes. All of a router’s interfaces
will not always run OSPF. An interface may connect to a LAN that runs RIP or
does not use dynamic routing. However, OSPF interfaces do not transmit LSAs
for a non-OSPF network. As far as peer routers are concerned, a connection
on a non-OSPF interface does not exist. If you want OSPF to consider such
connections when computing routes, you must redistribute connected routes
into OSPF. To enable the module to redistribute connected and static routes,
select the Connected and Static check boxes in the Network > Routing > OSPF
window.
By default, the TMS zl Module assigns routes redistributed into OSPF a metric
of 10. You can set a new default redistribution metric in step 2 below. The value
can be between 1 and 65535.
To redistribute routes into OSPF, do the following:
1. Click Network > Routing and click the OSPF tab.
2. For Default Metric, specify the cost for the redistributed routes. You can
also leave the default: 10.
3. Select the check boxes of the routes you want to redistribute.
4. Click Apply My Changes.
