Summarization solution

Summarization solution
You should’ve noticed in Figure 10.11 that Area 1 has the address 172.16.168.0 /24. If you just
set up normal redistribution between OSPF 1 and RIPv1, that route would not be redistributed.
So what we need to do is create an area range on R3 to summarize Area 1 to 172.16.0.0 /16. Once
the area range is set up, then redistribution can be configured and the route will be redistributed.
Here’s the configuration that would accomplish this:
R3#conf t
Enter configuration commands, one per line. End with CNTL/Z.
R3(config)#router ospf 1
R3(config-router)#area 1 range 172.16.0.0 255.255.0.0
R3(config-router)#^Z
R3#
R1#conf t
Enter configuration commands, one per line. End with CNTL/Z.
R1(config)#router rip
R1(config-router)#redistribute ospf 1 metric 1
R1(config-router)#^Z
R1#

Configuring Redistribution 351
Now let’s look at the option of creating a static route pointing to null0. We will first need
to configure on R1 a static route for 172.16.0.0 255.255.0.0 pointing to null0. We would then
redistribute the static route into RIP. The following is the configuration to accomplish this:
R1#conf t
Enter configuration commands, one per line. End with CNTL/Z.
R1(config)#ip route 172.16.0.0 255.255.0.0 null0
R1(config)#router rip
R1(config-router)#redistribute static metric 1
R1(config-router)#^Z
R1#
This scenario would accomplish the same task as the first. The method you use is up to you.
