Interior Gateway Protocols
Route Re-Distribution
RIP and OSPF can be enabled simultaneously on the switch. Route re-distribution allows the switch to
exchange routes, including static routes, between the three routing protocols. Figure 48 is an example of
route re-distribution between an OSPF autonomous system and a RIP autonomous system.

Configuring Route Re-Distribution
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.
