DYNAMIC ROUTING

Dynamic Routing (Router RIP)

Dynamic Routing Protocol adalah Routing protokol yang memungkinkan network admin untuk mensetup jaringan tanpa harus mengupdate konten dari routing table secara manual bila terjadi perubahan. Berbeda dengan static routing yang mengharuskan admin untuk merubah route atau memasukkan command secara manual di router tiap kali terjadi perubahan jalur. Dynamic routing protocol mengkalkulasi metic yang terdapat pada satu atau lebih jalur secara automatis dengan algoritma yang dimilikinya.
Pada kesempatan kali ini akan kita bahas materi terkait CISCO router menggunakan tipe routing dinamis.

cara konfigurasinya adalah sebagai berikut :
KONFIGURASI ROUTER1

Kemudian jangan lupa untuk menkonfigurasi IP Address komputer client sesuai dengan topologi jaringan yang telah di design sebelumnya. Dan jangan lupa untuk melakukan test ping untuk memastikan koneksi antar network.
PC0>ping 172.30.0.2

Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 219ms, Maximum = 250ms, Average = 238ms
PC0>tracert 172.30.0.2
Tracing route to 172.30.0.2 over a maximum of 30 hops:
1 63 ms 94 ms 78 ms 192.168.1.1
2 125 ms 125 ms 125 ms 202.110.10.2
3 156 ms 141 ms 125 ms 172.18.0.2
4 234 ms 218 ms 187 ms 172.30.0.2
Trace complete.
Dengan demikian sudah dapat kita hubungkan antara PC0 pada network 192.168.1.0/24 dengan network PC4 yang memiliki network 172.30.0.0/16
Untuk PC yang lain silahkan di lakukan test ping/tracert sendiri ya…!!!good luck..
