Thisis called also Router-on-a-stick. This configuration is usually asked as a question in CCNA exams, so I hope it will be helpful for people preparing for certification. Lets see the diagram below to get us started: A Cisco Layer 2 switch carries two VLANs (VLAN 10 - RED and VLAN 20 - GREEN) with two hosts connected to them as shown on TestingVLAN configuration. Access PC's command prompt to test VLAN configuration. Double click PC-PT and click Command Prompt. We have two VLAN configurations VLAN 10 and VLAN 20. Let's test VLAN 10 first. In VLAN 10 we have three PCs with IP addresses , 10.0.0.3 and 10.0.0.4.

What is a characteristic of legacy inter-VLAN routing? Only one VLAN can be used in the topology. The router requires one Ethernet link for each VLAN.* The user VLAN must be the same ID number as the management VLAN. 1 Define the trunk to use the 802.1q protocol. 2) Set the specific port to trunk mode. 3) Enable the spanning-tree portfast trunk function to ensure the port will forward packets immediately when connected to a device e.g router. Note: The spanning-tree portfast trunk command should never be used on ports that connect to another switch, to Konfigurasiswitch Klik Switch untuk atur CLI (untuk mengaktifkan Switch tersebut), dengan cara, klik pada Switch - pilih CLI.

Switch (config)#vlan 2 (Nama Vlan yang nanti dibuat) Postedby 2 years ago Here is an Edge Router ER-8 connected to WAN on one hand, and via 1G ports on the other hand to two UniFi Switches 16XG which in turn have a number of servers, VMs and clients connected to them via 10G (both fibre and copper). InterfaceFa0/48 of the Layer3 switch is configured as a Routed Port with IP address and connected to ASA inside interface (10.0.0.2). Two Vlans need to be created on the L2 and L3 switches, Vlan10 and Vlan20. Of course you can expand this scenario with more Vlans and more Layer 2 switches as needed. 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.

While echoing Ron and John's comments that there is no universal "best practice" here and there's only what's best for you, I'd like to propose an alternative solution that you haven't mentioned yet. EdgeRouter does support bonding/link aggregation using Link Aggregation Control Protocol LACP. However, in older EdgeRouters, this traffic was not eligible for offloading, which meant bonding for example 4 gigabit ports wouldn't result in 4Gbps of bandwidth. It would produce redundancy, but some bandwidth less than 4Gbps, possibly simply 1Gbps. However, according to this page, newer ER-X, ER-X-SFP, and EP-R6 EdgeRouters support offloading, so aggregating 4 gigabit ports should result in 4Gbps or very near it, allowing for some losses. So, in theory, if you had one of the newer EdgeRouters, and you didn't need certain mutually-exclusive protocols, and your network topology supported it, you could do the following Bond X ports on the router to support XGbps of bandwidth and also redundancy Bond X ports on the switch in the same way Connect X ethernet cables between the bonded router ports and the bonded switch ports Configure your VLANs on the single bonded interface on the router and switch I say this in a rather nebulous way; there are a lot of steps to this, clearly Through this configuration, all the VLANs would be able to take advantage of up to XGbps of bandwidth between the VLANs for allowed traffic, so that you wouldn't have saturated links using all 1Gbps and bottlenecked while other links used only a few Mbps and remained essentially unitized. I want to connect two routers to a switch which will then be connected to a modem. Now as far as I know a switch does not do network translation and this won't work with one IP address. So I bought two addresses at my ISP. Attached is a simple schematic that explains what I want to do. Is there any additional configuration needed on either of the routers Linksys WRT54GL to make this work or will it "Just Work"? slhck222k70 gold badges603 silver badges590 bronze badges asked May 29, 2012 at 958 5 This should just work. But i would make sure router 1 and router 2 client sides are on different subnets. answered May 29, 2012 at 1005 SibsterSibster8144 silver badges8 bronze badges 1 EDIT Apparently I was wrong, you can get two different IP addresses while using one Modem to connect. When I tried doing it, it didn't work, so maybe it depends on the ISP or the modem, or maybe I didn't configure it properly... You can use the Routers to manage the clients in two subnets and configure the routers separately. For example, you can use one router to configure a Wireless network and the other to configure a LAN network. answered May 29, 2012 at 1104 ShaharShahar3461 gold badge4 silver badges14 bronze badges 3 it's just work... because switch is device to share connection. You must setting routing table and NAT for routers. in the computer client, you must fill gateway with IP address of router... answered May 31, 2012 at 946 This question is really an old question, Hope you have already solved it, but I have some ideas to share with you. You are talking about 2 physically separate routers connecting to PoE switch. Yes, that is possible. You create 2 vlans on the switch. Lets say you create vlan 100 and 200, then add port,lets say 10 to vlan 100 and port 20 to vlan 200. Now you have one PC connected to port 10 and one PC connected to port 20. And don't forget to assign the IP address. answered Jul 11, 2016 at 235 Mark TwainMark Twain2541 silver badge5 bronze badges
