ThisVLAN filtering configuration example applies to InterVLAN Routing setup. /interface ethernet switch vlan add ports=switch1-cpu,ether6 vlan-id=200 add ports=switch1-cpu,ether7 vlan-id=300 add ports=switch1-cpu,ether8 vlan-id=400. Option 1: disable invalid VLAN forwarding on specific ports (more common): LegacyInter-VLAN Routing (4.1.2) The first inter-VLAN routing solution relied on using a router with multiple Ethernet interfaces. Each router interface was connected to a switch port in different VLANs. The router interfaces served as the default gateways to the local hosts on the VLAN subnet. BROADCASTDOMAIN DENGAN VLAN DAN ROUTER 1) Tanpa VLAN atau dengan kata lain satu VLAN. Satu network IP. 2) Dengan VLAN. Switch di konfigurasi dimana tiap portnya dapat ditentukan menjadi sebuah VLAN. Bagaimana broadcast domain pada kedua macam network tersebut? 1) Tanpa VLAN Satu link per VLAN atau single VLAN Trunk 2) Dengan VLAN /8 10 2Answers. Sorted by: 1. You are using the switch as a layer-3 switch (router), but the ip default-gateway command is for a layer-2 switch for the 10.10.1.1/24 network on VLAN 1. You do not use that command with IP routing. Cisco has a document that explains the differences: Configuring a Gateway of Last Resort Using IP Commands. Step1: Configure subinterfaces on R1 using the 802.1Q encapsulation. a. Create the subinterface G0/0.10. Set the encapsulation type to 802.1Q and assign VLAN 10 to the subinterface. Refer to the Address Table and assign the correct IP address to the subinterface. R1 (config)# int g0/0.10 R1 (config-subif)# encapsulation dot1Q 10 R1 (config Therethree type of VTP modes. VTP Server: The default mode. When you make a change to the VLAN configuration on a VTP server, the change is propagated to all switches in the VTP domain. VTP messages are transmitted out of all the trunk connections. In Server mode we can create, modify, and delete VLANs. VTP Client: cannot make changes to the Notall devices with a switch chip are capable of VLAN switching on a hardware level, check the supported features for each switch chip, the compatibility table can be found here.If a device has VLAN table support, then it is capable of VLAN switching using the built-in switch chip.You can check the device's switch chip either in the provided link or by using /interface ethernet switch print Yourrouter only knows about VLAN 1 from your switch because they are both on VLAN 1 so you also have to tell the router how to reach the other VLANs on your switch by setting static routes on your router for each of these VLANs. ip route 255.255.255. 10.0.1.1 for VLAN 2. ip route 10.0.3.0 255.255.255. 10.0.1.1 for VLAN 3.

Im trying to set up 2 VLANS on a topology, that consists of 4 PCs, 2 Switches and 1 Router. Task is , that 2 PCs that go to 1 switch run on separate Vlans, VLAN 10 and VLAN 20, and than on another Switch situation is the same. I have configured encapsulation on router for desired subinterfaces, ports from switch to router are set to trunk. Ports on switch are assigned to relevant VLAN. Still nothing is working. Could anyone advice the right way to go? Asked 5 years, 9 months ago Viewed 6k times I'm trying to understand the specifics of trunking a VLAN on two switches. Say I have two switches, both hosting half of VLAN 3. Switch 1 Ports 0-5 on VLAN 3, Port 6 is Trunk Switch 2 Ports 0-5 on VLAN 3, Port 6 is Trunk Do the two switches know what the MAC addresses are of the devices connected to the other switch which are in the same VLAN, or do the switches just know that Port 6 is a VLAN 3 trunk and when they receive a broadcast frame, they just flood the frame to the trunk port with the VLAN tag and expect the switch on the other end to deal with it? Ron Maupin♦ gold badges113 silver badges190 bronze badges asked Sep 11, 2017 at 1511 When a frame enters a switch, the switch will take the source MAC address and update its MAC address table with the interface where the frame entered the switch. That interface can be an access or trunk interface. Broadcast or unknown unicast frames will be sent to all interfaces except the one where the frame entered the switch, including access and trunk interfaces. Known unicast frames will be sent to the switch interface indicated in the switch MAC address table, whether an access or trunk interface. answered Sep 11, 2017 at 1516 Ron Maupin♦Ron gold badges113 silver badges190 bronze badges 6 VLAN3 is just a subnet or another network. Say you have vlan 1 and vlan 3 is Each device in vlan 3 will get the IP. That IP is assigned to the MAC address of the end device This is held in the arp table on a layer 3 device. Only the switch, as it is a layer 2 device, only knows the MAC address of the devices directly attached to it. A Trunk port allows for multiple networks or VLANS to communicate over the same port, But without a layer 3 they cannot talk to one another. A broadcast will be sent to any device on that VLAN or network. It doens't care if it's on switch one or two. answered Sep 11, 2017 at 1518 3 There's 2 thing in your question. First if you consider a single vlan, the port 6 being a trunk is not mandatory, setting the port 6 of both switch as VLAN3 will work. A trunk port has interest when you have multiples vlan on a switch, this mean you have made partitions on your switch, port 1 to 5 on VLAN3, port 7 to 12 on VLAN 4 for example, and you configure your port 6 as trunk to transport vlan 3 and 4. You may achieve the same thing without a trunk port if you keep port 6 in vlan 3 and use port 12 in VLAN 4 to link the two switches for example. A switch records incoming mac address on a port, such that when a packet is directed to a mac address it know where to send it, when it don't know or if it's a broadcast it send it on all ports within the same vlan, trunk included and the switch receiving the packet will scan it's own table before forwarding the packet to the correct port if already know or on all port within the vlan if the mac address is unknown or broadcast. Mainly a vlan is a virtual switch within the switch and the trunk is an aggregation of "virtual ports" to transport multiple vlans on a single link trunk on multiple links are trunks made on port aggregation LACP and are another subject. answered Sep 11, 2017 at 1541 "Switch 2 Ports 0-5 on VLAN 3, Port 6 is Trunk" .. Switch 2 knows that Vlan 3 information on sw1 from switch 1 Port6 mac -address . Through this mac-address frame is forwarded to switch2 from switch 1 After frames is in switch 2 . Traffic will further checks for mac -address table in switch 2, with the reference to this mac -address table frame is forwarded on required interfàce where destination host is connected. answered Dec 10, 2020 at 1150 Sagar UragondaSagar Uragonda8371 gold badge15 silver badges73 bronze badges
