Redistributing OSPF Routes

Various routing protocols discover routes in different ways. Some routing
protocols produce more reliable routes in certain topologies than other rout-
ing protocols can. For some networks, you might need to use several routing
protocols. If you use both OSPF and RIP on the network, the ProCurve Secure
Router can include routes discovered by OSPF in RIP updates. To enable this
capability, enter the following command from the RIP configuration mode
context:
Syntax: redistribute ospf [metric <value>]
The metric determines the number of hops that RIP reports to other routers
for that destination. If you do not specify a metric, the ProCurve Secure Router
OS automatically assigns OSPF routes the global default metric for RIP. (By
default, this metric is zero.)
Redistributing Static Routes
You can also redistribute routes that were manually added to the routing table:
Syntax: redistribute static [metric <value>]
Again, the metric is the global default value unless you manually enter a
different value with the metric keyword.
The ProCurve Secure Router will only redistribute a static route for which you
have indicated a next-hop address rather than a forwarding interface.
Enabling and Disabling Route Summarization for Classful
Subnets
RIP supports route summarization for classful subnets only. A router uses
summarization to advertise a route to all hosts in a class A, B, or C network
with a single routing table entry. This entry specifies the network address and
the classful subnet mask. For example, without route summarization, RIP
would need to broadcast the following:
Destination IP Address
10.2.0.0 255.255.0.0
10.3.0.0 255.255.0.0
10.4.0.0 255.255.0.0
10.5.0.0 255.255.0.0
