Configuring and Naming Static Routes on Cisco Routers

Objective

The objective of this lab exercise is to configure named static routes via next-hop IP addresses on interfaces connected to a switch between two routers. This lab also covers the validation of the configured static routes.
This lab will not work on Packet Tracer.

Purpose

Static route configuration is a fundamental skill for network engineers. There are various methods to configure static routes on a Cisco router, each with its pros and cons. Naming static routes allows for easy identification of their purposes when viewing router configurations. As a Cisco engineer or a CCNA candidate, you should be able to configure named static routes using any available methods in Cisco IOS.

Lab Topology

Use the following topology to complete this lab exercise:

Image 1

Task 1: Configure Hostnames

Objective: Set hostnames on R1, R2, and SW1 as illustrated in the topology.

Configuration:

R1#configure terminal
R1(config)#hostname R1
R1(config)#end

R2#configure terminal
R2(config)#hostname R2
R2(config)#end

SW1#configure terminal
SW1(config)#hostname SW1
SW1(config)#end

Task 2: Configure VTP and VLAN

Objective: Set SW1 as a VTP server, create VLAN 10 named STATIC, and assign ports FastEthernet0/1 and FastEthernet0/2 to this VLAN.

Configuration:

SW1#configure terminal
SW1(config)#vtp mode server
SW1(config)#vtp domain cisco
SW1(config)#vlan 10
SW1(config-vlan)#name STATIC
SW1(config-vlan)#exit
SW1(config)#interface FastEthernet0/1
SW1(config-if)#switchport mode access
SW1(config-if)#switchport access vlan 10
SW1(config-if)#exit
SW1(config)#interface FastEthernet0/2
SW1(config-if)#switchport mode access
SW1(config-if)#switchport access vlan 10
SW1(config-if)#end

Task 3: Configure IP Addresses

Objective: Configure IP addresses 172.27.32.1/30 on R1 and 172.27.32.2/30 on R2's Fa0/0 interfaces. Also, configure the Loopback interfaces on R1.

Configuration:

R1#configure terminal
R1(config)#interface FastEthernet0/0
R1(config-if)#ip address 172.27.32.1 255.255.255.252
R1(config-if)#no shutdown
R1(config-if)#exit
R1(config)#interface Loopback100
R1(config-if)#ip address 10.88.100.1 255.255.255.224
R1(config-if)#exit
R1(config)#interface Loopback101
R1(config-if)#ip address 10.99.100.1 255.255.255.224
R1(config-if)#end

R2#configure terminal
R2(config)#interface FastEthernet0/0
R2(config-if)#ip address 172.27.32.2 255.255.255.252
R2(config-if)#no shutdown
R2(config-if)#end

Task 4: Configure Named Static Routes

Objective: On R2, configure a static route named LAN-ROUTE via FastEthernet0/0 with a next-hop IP address of 172.27.32.1 to the 10.88.100.0/27 subnet. Configure a static route named WAN-ROUTE via Serial0/0 with a next-hop IP address of 192.168.7.1 to the 10.99.100.0/27 subnet. Verify your static route configuration.

Configuration and Verification:

R2#configure terminal
R2(config)#ip route 10.88.100.0 255.255.255.224 FastEthernet0/0 172.27.32.1 name LAN-ROUTE
R2(config)#ip route 10.99.100.0 255.255.255.224 FastEthernet0/0 172.27.32.1 name WAN-ROUTE
R2(config)#end

R2#show ip route
Codes: C - connected, S - static, 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
       i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS leve
l-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

     172.27.0.0/30 is subnetted, 1 subnets
C       172.27.32.0 is directly connected, FastEthernet0/0
     10.0.0.0/27 is subnetted, 2 subnets
S       10.99.100.0 is directly connected, FastEthernet0/0
S       10.88.100.0 is directly connected, FastEthernet0/0

Note: The names configured on the static routes do not show in the output of the show ip route command, but they appear in the running configuration. Naming static routes helps in identifying their purposes, especially when numerous static routes are configured. Use the show running-config | include route command to filter route statements:

R2#show running-config | include route
ip route 10.88.100.0 255.255.255.224 FastEthernet0/0 name LAN-ROUTE
ip route 10.99.100.0 255.255.255.224 FastEthernet0/0 name WAN-ROUTE

Task 5: Verification

Objective: Ping each Loopback interface configured on R1 from R2 to verify your static route configuration.

R2#ping 10.88.100.1

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.88.100.1, timeout is 2 seconds:
.!!!!
Success rate is 80 percent (4/5), round-trip min/avg/max = 20/28/36 ms
R2#ping 10.99.100.1

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.99.100.1, timeout is 2 seconds:
.!!!!
Success rate is 80 percent (4/5), round-trip min/avg/max = 8/14/28 ms
