Tugas InterVLAN + OSPF dengan dynamips!?!

Filed under: linux, cisco

Sekarang saya mencoba konfigurasi VLAN dengan menggabungkan routing protocol OSPF. Postingan sebelumnya jg pernah saya bahas ttg VLAN, cmn saya menggunakan boson. Nah, kali ini kita menggunakan dynamips baik switching dan routingnya, dan pembagian IPnya kita menggunakan VLSM (Variable Length Subnet Mask). Ini penambahan2 yg saya lakukan dari postingan saya sebelumnya yg bertema Belajar Setting VLAN. Topology yg saya gunakan sangat sederhana sekali, topologi dan VLSMnya bisa dilihat dibawah ini:

Topologinya VLAN + OSPF

VLSM

Bila teman2 melihat disitu ada VLAN 10 dengan 20 user.. Nah, itu hanya perumpamaan aja koq. Disitu sengaja saya buat 1 komputer aja utk kegunaan verying nntinya. Terus, kan ada tuch yg "fa0/0.xx" itu maksudnya adalah sub-interface dari fa0/0, yg "xx" itu disamakan dengan nomor VLANnya. Jadi klo "fa0/0.10" berarti itu sub-interface utk si VLAN 10.
Sekarang kita buat pembagian2 IPnya di setiap devices:

1. Serial 1/1 di R1 = 192.168.1.105 ; SubnetMask (SM) = 255.255.255.252
2. Fastethernet 0/0.10 di R1 = 192.168.1.1 ; SM = 255.255.255.224
3. Fastethernet 0/0.20 di R1 = 192.168.1.33 ; SM = 255.255.255.224
4. Fastethernet 0/0.30 di R1 = 192.168.1.65 ; SM = 255.255.255.240
5. Serial 1/1 di R2 = 192.168.1.106 ; SM = 255.255.255.252
6. Fastethernet 0/0.40 di R1 = 192.168.1.81 ; SM = 255.255.255.240
7. Fastethernet 0/0.50 di R2 = 192.168.1.97 ; SM = 255.255.255.248
8. IP di PC1 di VLAN 10 = 192.168.1.5 ; SM = 255.255.255.224 ; Gateway (GW) = 192.168.1.1
9. IP di PC2 di VLAN 20 = 192.168.1.35 ; SM = 255.255.255.224 ; GW = 192.168.1.31
10. IP di PC3 di VLAN 30 = 192.168.1.70 ; SM = 255.255.255.240 ; GW = 192.168.1.65
11. IP di PC4 di VLAN 40 = 192.168.1.85 ; SM = 255.255.255.240 ; GW = 192.168.1.81
12. IP di PC5 di VLAN 50 = 192.168.1.100 ; SM =255.255.255.248 ; GW = 192.168.1.97

Nah, ini file vlan_ospf.net saya :

autostart = false

[localhost]

   [[3660]]
    image = /opt/images/c3660-is-mz.124-8.bin
    ram = 96

   [[3640]]
    image = /opt/images/c3640-is-mz.122-15.T8.bin
    ram = 64

   [[2610]]
    image = /opt/images/c2600-i-mz.113-4.t1.image
    ram = 16
    slot1 = NM-1E
    idlepc = 0×801ea000

   
   [[router R1]]
    s1/0 = R2 s1/1
    F0/0 = SW1 F1/0
    console = 5000
    model = 3640
    idlepc = 0x604d3af4

   [[router R2]]
    model = 3640
    F0/0 = SW2 F1/0
    console = 5001
    idlepc = 0x604d3b30

   [[router SW1]]
    model = 3660
    slot1 = NM-16ESW
    console = 5002
    idlepc = 0x6058c480
    F1/1 = PC1 e1/0
    F1/2 = PC2 e1/0
    F1/3 = PC3 e1/0

   [[router SW2]]
    model = 3660
    slot1 = NM-16ESW
    console = 5003
    idlepc = 0x6058c480

   [[router PC1]]
    model = 2610
    console = 5004

   [[router PC2]]
    model = 2610
    console = 5005

   [[router PC3]]
    model = 2610
    console = 5006

   [[router PC4]]
    model = 2610
    e1/0 = SW2 F1/1
    console = 5007

   [[router PC5]]
    model = 2610
    e1/0 = SW2 F1/2
    console = 5008

Akhirnya semua konfigurasi awal udah keliatan neh.. tinggal konfigurasi si router, switch dan PC toch.. Nah, klo konfigurasi si router, switch dan PC itu bagiannya teman2.. kekeke.. Tugas yah!! Klo teman2 ada yang nggak mengerti cara konfigurasinya bisa ditanya koq lewat YM ataupun lewat comment. Saya yakin teman2 pasti bisa..!!!
InsyaALLAH dalam jangka waktu 1 minggu kedepan akan saya postingkan konfigurasi2nya (semuanya), tp alangkah baiknya bila teman2 mencoba dulu sendiri, sekalian belajar toch.. :) .

Saya kasih contoh konfigurasi di PC1 yg VLAN 10 :

Router(config)#hostname PC1
PC1(config)#no ip routing
PC1(config)#ip default-gateway 192.168.1.1 255.255.255.224
PC1(config)#interface ethernet0/1
PC1(config-if)#ip address 192.168.1.5 255.255.255.224
PC1(config-if)#no shutdown

  1. Halo Ghozali,

    Mantab nian kofigurasi Dynagennya. Gw sendiri sih baru sekarang2 ini aja pake dynagen. Belom cadas….. Kalau saja lebih banyak orang2 Indonesia yang seperti ini, gw yakin Indonesia akan cepet maju (bukan hanya di bidang IT saja loh).

    Oh iya, skaligus ngejawab yg dari milis Indocisco. Iya, kompie gw yg di rumah masih pake 512 MB, dan gw lom manfaatin dynagen, masih murni pake dynamips dan belum di optimasi (idle-pc dan lain2).

    Klo di kantor, gw pake dynagen, kompie 1 GB, dan dah gw optimasi. Hm…. terasa enteng jg, paling klo pas ruternya booting ajah yg nyampe 100%. Abis itu… dingin lagi.

    OK d, oh ya, ada YM??? Kklo ada, kontak lwt japri yak…

    Kita tuker2 ngelmu (bukan ilmu pelet)…..

  2. Mas ghozali…
    mw tanya om…
    klo di dynamips kan ngrubah pc jd pc router cisco…
    nah klo pc kan interfacenya cm fast ethernet..
    mohon perncerahan om…
    makash bnyk…
    klo seandainya saya mw bwt lab jaringan WAN ttg frame relay itu kan harus ada interface serial..
    nah itu bagaimana kofigurasinya?
    apakah fast ethernet yang ada dalm pc diumpamakan sebagai serial?
    dalam contoh ini saya memakai 1 pc untuk 1 router dengan dynampis..
    saya menggunakan 3 pc router dynamips yang salin terhbung

  4. Usually, university teachers are willing to testify the academic essay writing technique of their students, however not all students can to write correctly because of lack of time or other things. Therefore, a classification essay writing service can aid to compose the argumentative term paper very fast.
