Using route policy in route redistribution
The following examples show some basic uses of route policy based on the figure below. (All subnets have 24-bit
masks.)

Each of the routing domains in
Figure 47: Network for redistribution example
on page 277 is defined with
simple VLANs and a basic routing configuration:
• In the RIP domains, the RIP protocol is assigned to each VLAN that a router connects to.
• Routers in the RIP domains redistribute connected routes—this is the default setting when RIP is enabled.
• For simplicity, all VLANs in the OSPF domain are assigned to the backbone area (area 0.)
• Border routers (North and South) implement both RIP and OSPF protocols.
