Objective
To use dynamic and static routing to provide network connectivity.
Scenario
Given a 199.1.10.0 address provide four subnets to support at least 25 hosts. The current
network requires two of the networks and the other two will be used in the future. Use
RIP and connect to a web server with the IP address of 200.200.200.5. The
200.200.200.0 network is not to be advertised by the ISP router. Use a static route to
reach this network. Configure all routers with a hostname and use “cisco’ as the
password for console, enable secret and telnet access.
Step 1
Cable the labs according to the topology in the diagram. Attach a workstation to the
Fastethernet 0 interface on RouterA. Configure the workstation with the appropriate IP
address. Host A and the web server are to be assigned the fifth usable IP address on the
assigned subnet.
Step 2
ISP router configuration
On the ISP router configure the hostname, console password, enable secret password,
and telnet access.
Router>enable
Router#configure terminal
Router(config)#hostname ISP
ISP(config)#enable secret cisco
ISP(config)#line console 0
ISP(config-line)#login
ISP(config-line)#password cisco
ISP(config-line)#exit
ISP(config)#line vty 0 4
ISP(config-line)#login
1-1

ISP(config-line)#password cisco
ISP(config-line)#exit
ISP(config)#
Step 3
Configure the interfaces on the ISP router.
After calculating the IP address requirements the result is that the network between ISP
and RouterA is 199.1.10.0. The serial interface on the ISP router is assigned the first
usable IP address on the connected subnet. Use the following commands to configure
the IP addresses on the ISP router interfaces:
ISP(config)#interface fastethernet 0
ISP(config-if)#ip address 200.200.200.1 255.255.255.0
ISP(config-if)#no shutdown
ISP(config-if)#exit
ISP(config)#interface serial 0
ISP(config-if)#ip address 199.1.10.1 255.255.255.224
ISP(config-if)#clock rate 56000
ISP(config-if)#no shutdown
ISP(config-if)#exit
ISP(config)#
Step 4
Enable RIP on the ISP router.
Configure RIP routing protocol on this router with the following commands.
ISP(config)#router rip
ISP(config-router)#network 199.1.10.0
ISP(config-router)#exit
Step 5
RouterA configuration
On RouterA configure the hostname, console and enable secret passwords, and telnet
access.
Router>enable
Router#configure terminal
Router(config)#hostname RouterA
RouterA(config-line)#enable secret cisco
RouterA(config)#line console 0
RouterA(config-line)#login
RouterA(config-line)#password cisco
RouterA(config-line)#exit
RouterA(config)#line vty 0 4
RouterA(config-line)#login
RouterA(config-line)#password cisco
RouterA(config-line)#exit
RouterA(config)#
Step 6
Configure the interfaces on RouterA.
Assign the second usable IP address to the serial 0 interface. Assign the first usable IP
address on the Fastethernet interface .Use the following commands to configure the
interfaces on RouterA.
RouterA(config)#interface fastethernet 0
RouterA(config-if)#ip address 199.1.10.33 255.255.255.224
RouterA(config-if)#no shutdown
RouterA(config-if)#exit
RouterA(config)#interface serial 0
RouterA(config-if)#ip address 199.1.10.2 255.255.255.224
1-2

RouterA(config-if)#no shutdown
RouterA(config-if)#exit
Step 7
Enable RIP on RouterA.
Configure RIP routing protocol on RouterA with the following commands.
RouterA(config)#router rip
RouterA(config-router)#network 199.1.10.0
RouterA(config-router)#exit
RouterA(config)#exit
Step 8
Configure a static route
Use the show ip route command on RouterA. Do you see the network 200.200.200.0?
Answer: _no_
RouterA#show ip route
Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area
* - candidate default, U - per-user static route, o - ODR
P - periodic downloaded static route
Gateway of last resort is not set
199.1.10.0/27 is subnetted, 2 subnets
C
199.1.10.0 is directly connected, Serial0
C
199.1.10.32 is directly connected, FastEthernet0
Since the ISP router is not advertising the network 200.200.200.0 it will not appear in the
routing table on RouterA. Add a static route for 200.200.200.0 network on RouterA with
the following command.
RouterA#configure terminal
RouterA(config)#ip route 200.200.200.0 255.255.255.0 199.1.10.1
RouterA(config)#exit
RouterA#
Use the show ip route command to check if the route for network 200.200.200.0 is
now present in the routing table.
RouterA#show ip route
Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area
* - candidate default, U - per-user static route, o - ODR
P - periodic downloaded static route
Gateway of last resort is not set
S
200.200.200.0/24 [1/0] via 199.1.10.1
199.1.10.0/27 is subnetted, 2 subnets
C
199.1.10.0 is directly connected, Serial0
C
199.1.10.32 is directly connected, FastEthernet0
Use the ping command to test connectivity to the web server.
RouterA#ping 200.200.200.5
Sending 5, 100-byte ICMP Echos to 200.200.200.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 32/32/32 ms

Step 9
Check the routing on ISP
Now make sure the ISP router has learned about the local network on RouterA. Use the
show ip route command on the ISP router.
ISP#show ip route
Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area
* - candidate default, U - per-user static route, o - ODR
P - periodic downloaded static route
Gateway of last resort is not set
C
200.200.200.0/24 is directly connected, FastEthernet0
199.1.10.0/27 is subnetted, 2 subnets
C
199.1.10.0 is directly connected, Serial0
R
199.1.10.32 [120/1] via 199.1.10.2, 00:00:19, Serial0
Use the ping command to test the connectivity with Host A.
ISP#ping 199.1.10.38
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 199.1.10.38, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 32/34/36 ms
Verify that Host A can communicate with the web server. From the command prompt on
Host A ping the web server.
