In a typical network, everything on the same side of the router is all part of the same broadcast domain. A switch that you have implemented VLANs on has multiple broadcast domains, similar to a router. But you still need a router (or Layer 3 routing engine) to route from one VLAN to another -- …
Oct 20, 2016 How To Configure VLANs on Cisco Router. Hi Cathbert, Cisco routers do not run VTP on their routed ports, and thus have no way of dynamically learning VLAN information. Certain routers, such as 29xx and 39xx routers can be equipped with switch modules, where all ports act as switched ports. On these ports, you … EdgeRouter - Create Virtual Interfaces with VLAN IDs Adding a VIF to an Ethernet Interface. Follow the steps below to create a virtual interface with a VLAN ID of 10 and address 10.0.10.1/24 on the eth1 interface:
In addition to switches, Cisco has supported ISL with router connections since Cisco IOS Release 11.1. ISL implements support for VLAN information in a completely different manner than IEEE 802.1Q; instead of inserting a header into the Ethernet frame it encapsulates the entire existing Ethernet frame into an ISL frame with a new header used to transport the Ethernet frame between switches.
Communication between VLANs require layer 3 devices like router or layer 3 switch. VLANs can be used for many purpose, logically grouping users, separating types of traffic, access control, security, quality of service and others. As shown in figure 1, a single Cisco switch is configured with two VLANs, VLAN – …
That’s exactly I’m looking for. I want to setup a Tagged, Multi-VLAN Trunk Line Between one of the router’s LAN ports and a Netgear GS116E switch. The router needs to provide DHCP IP addresses (and Gateway information) in different subnets for each of the VLANs. For example: VLAN 1: 192.168.1.1/24. VLAN 2: 192.168.2.1/24. VLAN 3: 192.168
