Hands-On Exploration

Networking is not just theoretical knowledge; it’s a practical skill. Establishing a home lab environment or leveraging simulation tools is crucial to gaining hands-on experience. This practical insight not only aids in exam preparation but proves invaluable in real-world scenarios, bridging the gap between theory and application.

Advanced Configuration Example:

Implementing OSPF Routing with Security Features

Let’s delve into an advanced configuration example involving the implementation of OSPF (Open Shortest Path First) routing with security features on two Cisco routers:

CCNA OSPF

Router 1 Configuration:

R1#sh ip ospf neighbor

Neighbor ID     Pri   State           Dead Time   Address         Interface

2.2.2.2           1   FULL/DR         00:00:39    192.168.0.2     Ethernet0/0

R1#sh ip ro ospf      

Codes: L – local, 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, H – NHRP, l – LISP

       a – application route

       + – replicated route, % – next hop override

Gateway of last resort is not set

      2.0.0.0/32 is subnetted, 1 subnets

O IA     2.2.2.2 [110/11] via 192.168.0.2, 00:01:42, Ethernet0/0

R1#ping 2.2.2.2 so lo0

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 2.2.2.2, timeout is 2 seconds:

Packet sent with a source address of 1.1.1.1

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/2 ms

R1#sh run | s ospf

 ip ospf message-digest-key 12 md5 CCNAmysecureKey

router ospf 1

 router-id 1.1.1.1

 area 0 authentication message-digest

 network 1.1.1.1 0.0.0.0 area 1

 network 192.168.0.0 0.0.0.255 area 0

interface Ethernet0/0

 ip address 192.168.0.1 255.255.255.0

end

Router 2 Configuration:

R2#sh ip ospf neighbor

Neighbor ID     Pri   State           Dead Time   Address         Interface

1.1.1.1           1   FULL/BDR        00:00:35    192.168.0.1     Ethernet0/0

R2#sh ip ro ospf

Codes: L – local, 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, H – NHRP, l – LISP

       a – application route

       + – replicated route, % – next hop override

Gateway of last resort is not set

      1.0.0.0/32 is subnetted, 1 subnets

O IA     1.1.1.1 [110/11] via 192.168.0.1, 00:02:53, Ethernet0/0

R2#ping 1.1.1.1 so lo0

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 1.1.1.1, timeout is 2 seconds:

Packet sent with a source address of 2.2.2.2

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/1 ms

R2#sh run | s ospf

 ip ospf message-digest-key 12 md5 CCNAmysecureKey

router ospf 1

 router-id 2.2.2.2

 area 0 authentication message-digest

 network 2.2.2.2 0.0.0.0 area 1

 network 192.168.0.0 0.0.0.255 area 0

R2#sh run int e0/0

Building configuration…

Current configuration : 118 bytes

!

interface Ethernet0/0

 ip address 192.168.0.2 255.255.255.0

 ip ospf message-digest-key 12 md5 CCNAmysecureKey

end

In this example, OSPF is configured between two routers, R1 and R2, both in backbone area . Security is enhanced by implementing OSPF message-digest authentication, adding an extra layer of protection to the OSPF routing process.

Community Connection
