  1. 1. CCNA3-1 Chapter 6 Inter-VLAN Routing Introducing Inter-VLAN RoutingIntroducing Inter-VLAN Routing
  2. 2. CCNA3-2 Chapter 6 • What is Inter-VLAN Routing? • Setiap VLAN memiliki unique broadcast domain. • Computers yang terdiri dari VLANs yang terpisah, secara default, tidak dapat berkomunikasi. • Setiap VLAN memiliki unique IP subnetwork. • Agar VLANs dapat saling berkomunikasi, kita membutuhkan router untuk menghubungkan broadcast domains dan unique IP subnetworks yang berbeda. • Oleh karena itu Inter-VLAN routing, merupakan sebuah process untuk melakukan forwarding traffic dari VLAN yang satu ke VLAN lainnya dengan menggunakan router. Introducing Inter-VLAN Routing
  3. 3. CCNA3-3 Chapter 6 • Ada beberapa Methods dari Inter-Vlan Routing ini, yaitu: 1. Traditional Inter-VLAN Routing. 2. Router-on-a-stick Inter-VLAN Routing. 3. Switch Based Inter-VLAN Routing. Introducing Inter-VLAN Routing
  4. 4. CCNA3-4 Chapter 6 • Traditional Inter-VLAN Routing: • One router interface per VLAN.

  5. 5. CCNA3-5 Chapter 6 • Traditional Inter-VLAN Routing: • Traditional routing membutuhkan routers yang memiliki multiple physical interfaces untuk memfasilitasi inter- VLAN routing. • Masing-masing interface di configured dengan IP address dengan subnetnya sendiri yang terkait pada VLAN tertentu. • Dalam configuration ini, network devices dapat menggunakan router sebagai gateway untuk mengaccess devices yang terhubung ke VLANs lainnya. Interfaces and Subinterfaces

  8. 8. CCNA3-8 Chapter 6 • Traditional Inter-VLAN Routing: • Traditional inter-VLAN routing menggunakan 1 physical interfaces per vlan. • Hal ini akan mengakibatkan keterbatasan dalam penggunaannya, semakin banyak vlan yang digunakan maka semakin banyak interface yang diperlukan. • Sementara routers memiliki batasan jumlah dari physical interfaces yang bisa digunakan. • Dan hal tersebut akan membutuhkan biaya yang mahal karena keperluan penambahan modul Ethernet/Fastethernet Interface.

  10. 10. CCNA3-10 Chapter 6 • Router-on-a-stick Inter-VLAN Routing: • Subinterfaces: • Overcomes the hardware limitation of a router. • Subinterfaces are software-based virtual interfaces that are assigned to physical interfaces. • Each subinterface is configured with its own IP address, subnet mask, and unique VLAN assignment. • Connected to a switch trunk link. • Functionally the same as using the traditional routing model.

  12. 12. CCNA3-12 Chapter 6 • Router-on-a-stick Inter-VLAN Routing: • Configuring Subinterfaces: • Similar to configuring physical interfaces. • Create the subinterface. • Assign it to a VLAN. • Assign an IP Address. • Enable the interface. Interfaces and Subinterfaces
  13. 13. CCNA3-13 Chapter 6 • Router-on-a-stick Inter-VLAN Routing: • Create the subinterface: • The syntax for the subinterface is always the physical interface followed by a period and a subinterface number. • The subinterface number is configurable, but it is typically associated to reflect the VLAN number. R1(config)#interface [interface].nn NOTE: The management VLAN must also be configured if you wish to use it on multiple switches that are not directly connected by trunk links. Interfaces and Subinterfaces
  14. 14. CCNA3-14 Chapter 6 • Router-on-a-stick Inter-VLAN Routing: • Assign it to a VLAN: • Before assigning an IP Address, the interface must to be configured to operate on a specific VLAN using the proper encapsulation. R1(config-subif)#encapsulation dot1q vlan-id Interfaces and Subinterfaces
  15. 15. CCNA3-15 Chapter 6 • Router-on-a-stick Inter-VLAN Routing: • Assign an IP Address: • The IP Address assigned here will become the default gateway for that VLAN. R1(config-subif)#ip address [address] [mask] Interfaces and Subinterfaces
  16. 16. CCNA3-16 Chapter 6 • Router-on-a-stick Inter-VLAN Routing: • Enable the interface: • Subinterfaces are not enabled individually. • When the physical interface is enabled, all associated subinterfaces are enabled. R1(config-if)#no shutdown Interfaces and Subinterfaces
