Because redistributed routes are external, you cannot redistribute routes on
a stub router. When you redistribute any routes, even connected ones, into
OSPF, the router is automatically considered an ASBR.

Redistributing RIP Routes

When a ProCurve Secure Router connects an OSPF network to an external
network, it acts as an ASBR. Such a router often needs to redistribute external
routes into the network. You can have the ASBR generate a default route or
route summaries for external routes as described in "Generating a Default
External Route (ASBR)" on page 13-51. This option keeps overhead at a
minimum.
However, if the external routes are limited, you can simply have the router
redistribute them into OSPF. For example, suppose that your router connects
to an external network that runs RIP. You can enable the router's WAN
interface to run RIP (see "Configuring RIP" on page 13-12) and then redistrib-
ute these routes into OSPF.
Move to the OSPF configuration mode context and enter:
ProCurve(config-ospf)# redistribute rip
If you do not want the redistributed routes to have the default cost of 20, add
a different metric. For example, to change the metric to 50, enter:
ProCurve(config-ospf)# redistribute rip metric 50
To limit the number of routes that the ASBR must advertise, you can configure
route summaries after redistributing the routes into OSPF. See "Configuring
Route Summaries for ASBRs" on page 13-52.

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.
From the OSPF configuration mode context, enter:
ProCurve(config-ospf)# redistribute connected
