Configuring Static Routing via IP addresses

Objective

The goal of this lab exercise is to configure static routes using next-hop IP addresses on interfaces connected to a switch between two routers. This lab also includes validating the configured static routes.

Purpose

Static route configuration is a fundamental skill for network engineers. There are several ways to configure static routes on a Cisco router, each with its pros and cons. As a Cisco engineer or a CCNA candidate, you are expected to know how to configure 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: Configure SW1 as a VTP server and configure VLAN10 named STATIC. Assign ports FastEthernet0/1 and FastEthernet0/2 to this VLAN 10.

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 10.100.1.1 255.255.255.0
R1(config-if)#exit
R1(config)#interface Loopback101
R1(config-if)#ip address 10.101.1.1 255.255.255.0
R1(config-if)#exit
R1(config)#interface Loopback102
R1(config-if)#ip address 10.102.1.1 255.255.255.0
R1(config-if)#exit
R1#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 Static Routes and Verify

Objective: On R2, configure static routes using the next-hop IP address 172.27.32.1 for all subnets on R1's Loopback interfaces. Validate connectivity.

Configuration and Verification:

R2#configure terminal
R2(config)#ip route 10.100.1.0 255.255.255.0 172.27.32.1
R2(config)#ip route 10.101.1.0 255.255.255.0 172.27.32.1
R2(config)#ip route 10.102.1.0 255.255.255.0 172.27.32.1

R2#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

     10.0.0.0/24 is subnetted, 3 subnets
S       10.100.1.0 [1/0] via 172.27.32.1
S       10.101.1.0 [1/0] via 172.27.32.1
S       10.102.1.0 [1/0] via 172.27.32.1
     172.27.0.0/30 is subnetted, 1 subnets
C       172.27.32.0 is directly connected, FastEthernet0/0

R2#ping 10.100.1.1

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.100.1.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 0/0/0 ms

R2#ping 10.101.1.1

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.101.1.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 0/0/0 ms

R2#ping 10.102.1.1

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.102.1.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 0/1/6 ms

Notes: Using an IP address for the next hop avoids the ARP timeout for the first packet, ensuring immediate connectivity.
