Static Routing On Cisco

Configure the IP addresses and enable the ports as shown on the topology above.
After configuring the only routes in the table will be the directly configured one as shown from the show ip route command on Kopsiro Router

Kopsiro#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 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, 2 subnets

C       10.10.10.0 is directly connected, FastEthernet0/0
C       10.10.11.0 is directly connected, FastEthernet0/1

Kopsiro Router for example needs to have networks 10.10.12.0/24 and 10.10.13.0/24 into its routing table.
To add other routes into the Routing table of the Routers

 Kopsiro Router,
Kopsiro(config)#ip route 10.10.12.0 255.255.255.0 10.10.10.2
Kopsiro(config)#ip route 10.10.13.0 255.255.255.0 10.10.11.2

Kapso Router
Kapso(config)#ip route 10.10.11.0 255.255.255.0 10.10.10.1
Kapso(config)#ip route 10.10.13.0 255.255.255.0 10.10.12.2

Kaptama Router
Kaptama(config)#ip route 10.10.11.0 255.255.255.0 10.10.13.1
Kaptama(config)#ip route 10.10.10.0 255.255.255.0 10.10.12.1

Cheptais Router
Cheptais(config)#ip route 10.10.10.0 255.255.255.0 10.10.11.1
Cheptais(config)#ip route 10.10.12.0 255.255.255.0 10.10.13.2

Apply the Show ip route command on every router and check the routes in the routing table with a code of S.
Example on Kapso Router
Kapso(config)#do 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 level-2
       ia - IS-IS inter area, * - candidate default, U - per-user static route
       o - ODR, P - periodic downloaded static route

     10.0.0.0/24 is subnetted, 4 subnets
C       10.10.10.0 is directly connected, FastEthernet0/0
S       10.10.11.0 [1/0] via 10.10.10.1

S       10.10.13.0 [1/0] via 10.10.12.2
Kapso(config)#
Ping Cheptais Router from Kapso Router
Kapso#ping 10.10.13.1 r 100

Type escape sequence to abort.
Sending 100, 100-byte ICMP Echos to 10.10.13.1, timeout is 2 seconds:
