### 1. Setup IP addresses on all routers. 20% A-B 192.168.1.0, B-C: 192.168.2.0, C-D: 192.168.3.0
Go into router 0 and open CLI

Router>enable
Router#conf t // enter "configure terminal" will work the same
Router(config)#int fa0/0
Router(config-if)#ip addr 192.168.1.1 255.255.255.0
Router(config-if)#no sh

exit router 0
Go into router 1 and open CLI

Router>ENABLE
Router#conf t // congfigure terminal will work the same
Router(config)#int fa0/0
Router(config-if)#ip addr 192.168.1.2 255.255.255.0
Router(config-if)#no sh
Router(config-if)#do show ip route
Router(config)#int fa0/1
Router(config-if)#ip addr 192.168.2.1 255.255.255.0
Router(config-if)#no sh

exit router 1
Go into router 2 and open CLI

Router>ENABLE
Router#conf t // congfigure terminal will work the same
Router(config)#int fa0/0
Router(config-if)#ip addr 192.168.2.2 255.255.255.0
Router(config-if)#no sh
Router(config-if)#do sh ip ro
Router(config)#int fa0/1
Router(config-if)#ip addr 192.168.3.1 255.255.255.0
Router(config-if)#no sh

exit router 2
Go into router 3 and open CLI

Router>ENABLE
Router#conf t // congfigure terminal will work the same
Router(config)#int fa0/0
Router(config-if)#ip addr 192.168.3.2 255.255.255.0
Router(config-if)#no sh
Router(config-if)#do sh ip ro

### 2. Setup RIP(Routing information Protocol) at Router 1 & 2. 40%

go into router 1

Router(config)#router rip // make sure it is Router(config)#
Router(config-router)#network 192.168.1.0
Router(config-router)#network 192.168.2.0

check for setup ip
Router#sh ip ro // R 192.168.3.0/24 [120/1] via 192.168.2.2, 00:00:25, FastEthernet0/1 will appear

go into router 2

Router(config)#router rip // make sure it is Router(config)#
Router(config-router)#network 192.168.2.0
Router(config-router)#network 192.168.3.0

Router(config-router)#do show ip r

check for setup ip
Router#sh ip ro // R 192.168.1.0/24 [120/1] via 192.168.2.1, 00:00:03, FastEthernet0/0 will appear

### 3. Setup a static route at A to 192.168.3.0, and ping it at A. 20%

go into router 0

Router(config)#ip route 192.168.2.0 255.255.255.0 192.168.1.2 // make sure its Router(config)#
Router(config)#ip route 192.168.3.0 255.255.255.0 192.168.1.2
Router(config)#do ping 192.168.2.0
Router(config)#do ping 192.168.3.0

### 4. Setup a default route at router D, ping 192.168.1.0 at D. 20%

go into router 3

Router(config)#ip route 0.0.0.0 0.0.0.0 192.168.3.1
Router(config)#exit
Router#ping 192.168.1.0
