Route Redistribution
ExtremeWare XOS 11.0 Concepts Guide 283
NOTE
All routers in the VLAN must have the same OSPF link type. If there is a mismatch, OSPF attempts to
operate, but it may not be reliable.
Route Redistribution
RIP and OSPF can be enabled simultaneously on the switch. Route redistribution allows the switch to
exchange routes, including static routes, between the routing protocols. Figure 50 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.
