OSPF

Route Redistribution

More than one routing protocol can be enabled simultaneously on the switch. Route redistribution
allows the switch to exchange routes, including static routes, between the routing protocols. Figure 70 is
an example of route redistribution between an OSPF AS and a RIP AS.

Configuring Route Redistribution

Exporting routes from one protocol to another and from that protocol to the first one are discreet
configuration functions. For example, to run OSPF and RIP simultaneously, you must first configure
both protocols and then verify the independent operation of each. Then you can configure the routes to
export from OSPF to RIP and the routes to export from RIP to OSPF. Likewise, for any other
combinations of protocols, you must separately configure each to export routes to the other.
Redistributing Routes into OSPF
Enable or disable the exporting of BGP, RIP, static, and direct (interface) routes to OSPF using the
following commands:
