2621A(config)#no ip route 172.16.30.0 255.255.255.0
172.16.10.2
2621A(config)#no ip route 172.16.40.0 255.255.255.0
172.16.10.2
2621A(config)#no ip route 172.16.50.0 255.255.255.0
172.16.10.2
Once the static routes are deleted from the configuration, you can add the
RIP routing protocol by using the router rip command and the network
command. The network command tells the routing protocol which network
to advertise. Notice that in the router configuration below the routing protocol
is not told which subnets to advertise; it is told the classful boundary.
RIP will find the subnets and advertise them.
2621A(config)#router rip
2621A(config-router)#network 172.16.0.0
2621A(config-router)#^Z

That’s it. Two commands, and you’re done—sure makes your job a lot
easier than when using static routes, doesn’t it? However, keep in mind the
extra router CPU process and bandwidth that you’re consuming.
To configure RIP on the 2501A router, you need to remove the three static
routes you added from the earlier example. Once you make sure no routes
are in the routing table with a better administrative distance than 120, you
can add RIP. Again, if you do not remove the static routes, RIP routes will
never be used on the router.

Enter configuration commands, one per line. End with
CNTL/Z.
