Only one of the router s physical interface is used.ġ2 INTER-VLAN ROUTING OPERATION MULTILAYER SWITCH INTER-VLAN ROUTING Multilayer switches can perform Layer 2 and Layer 3 functions, replacing the need for dedicated routers. VLAN members (hosts) are configured to use the subinterface address as a default gateway. Each subinterface is configured with an IP address from the VLAN it represents. Logical subinterfaces are created one subinterface per VLAN. One of the router s physical interfaces is configured as a 802.1Q trunk port so it can understand VLAN tags. Large networks with large number of VLANs required many router interfaces.ġ1 INTER-VLAN ROUTING OPERATION ROUTER-ON-A-STICK INTER-VLAN ROUTING The router-on-a-stick approach uses a different path to route between VLANs. Because the router interfaces were connected to VLANs and had IP addresses from that specific VLAN, routing between VLANs was achieved. Packets would arrive on the router through one through interface, be routed and leave through another.
Each VLAN was connected to a different physical router interface.
Konfigurasi VLAN bermanfaat untuk mengkontrol size broadcast domain dan menjaga trafik local Untuk dapat mengkoneksikan end-device didalam satu VLAN dengan VLAN lainnya dibutuhkan komunikasi intervlan InterVLAN membutuhkan interface fisik router atau subinterface router sebagai gateway masing-masing Penggunaan sub-interface router untuk inter-vlan disebut sebagai router-on-stick Sub-interface router untuk intervlan membutuhkan protocol trunking ISL atau 802.1qħ Router-on-stick 元 Switch dengan SVI Per-interface intervlan routing CARA KONFIGURASI INTERVLANĨ Pilih interface router Setting sub-interface KONFIGURASI ROUTER- ON-STICK Setting protocol trunking ISL atau 802.1qġ0 In the past: INTER-VLAN ROUTING OPERATION LEGACY INTER-VLAN ROUTING Actual routers were used to route between VLANs. Inter-VLAN routing is a process for forwarding network traffic from one VLAN to another, using a router.Ħ BAGAIMANA INTERLVLAN ROUTING BEKERJA? Device network yang berbeda VLAN tidak dapat berkomunukasi dengan device lainnya tanpa routing dan switch 元, yang berfungsi untuk merutekan trafik antar VLAN. Layer 3 switches with routing enabled have more Ethernet ports as well as the ability to route.Ģ.5 INTER-VLAN ROUTING OPERATION WHAT IS INTER-VLAN ROUTING? Layer 2 switches cannot forward traffic between VLANs without the assistance of a router. Multiple physical interfaces on the router would be faster than the router-on-a-stick design, but a router has a limited number of physical interfaces.
This design works, but does not scale well because all VLANs must traverse the one connection between the router and the switch. Explanation: A router-on-a-stick design is the same as having a trunked interface between the router and the switch.
