Workstations A B
IP 161.20.2.2 161.20.1.2
SM 255.255.255.0 255.255.255.0
GW 161.20.2.1 161.20.1.1
Step-by-Step Instructions:
1. Cable and set up the lab as shown.
2. Complete the basic router setup on each router.
3. Configure the interfaces on each router.
4. Configure the workstations. You should NOT be able to ping from workstation A to
anywhere. Silly billy…we haven’t configured a routing protocol yet.
5. So let’s fix that little problem here using RIP version 2. Configure the routing
protocol and advertise the router’s networks using RIP version 2 by doing this:
phiber(config)#router rip
phiber(config-router)#network 161.20.0.0
phiber(config-router)#version 2
And on the other router:
optik(config)#router rip
optik(config-router)#network 161.20.0.0
optik(config-router)#version 2
6. Now you should be able to ping from each workstation to the other workstation, to
the loopbacks on both routers and everywhere. BAM! Problem solved much easier
than with static routes. Yeah…it’s that easy. ☺
7. Now let’s take it up another level and add some more routers to our network (look for
the lab diagram at the end of this lab). One router will act as an ISP and the other will
be a new company we just acquired. They are running RIP on their network. The
boss their likes RIP because she is familiar with it so you decide to leave it intact.
But you need to be able to pass your routing information over your network so you
use your knowledge of the CISCO website and find out information about two
commands you can use to “redistribute” your routing protocol:
ip rip send version 1
ip rip receive version 1
8. Also you do not want your ISP to have the information about your network so you
decided to stop all routing table broadcasts out the serial interface on phiber. You
enter this command:
phiber(config)#router rip
phiber(config-router)#passive-interface serial0/1
