# Create DHCP Server and assign different Pools for the dealers In this example following ports are used for Each area will get different IP series from the mikrotik dhcp server. and we want to isolate the different network areas by breaking them in smaller segments. We have Mikrotik Router which is acting as a DHCP and PPPoE Server as well. To avoid broadcasting/flooding and above all for better better management +security and monitoring, we want to break the network in smaller segments. VLAN can help you in many situations like these or others. The main problem of any large network is broadcast and specially for network operators when any single user swap his wan router LAN cable to wan cable thus broadcast his router DHCP to operator network, or single user effected with virus/trojans broadcast to whole network. It is very useful for any network including large/small offices, ISP’s, Cable.Internet services providers etc. VLANs allow you to break up devices on your network regardless of their location. VLAN membership can be configured through software instead of physically relocating devices or connections. Virtual LANs (VLANs) are a solution to allow you to separate users into individual network segments for security and other reasons. If you attempt to create a VLAN with an existing VLAN ID, the switch goes into the VLAN submode but does not create the same VLAN again.~!~ Mikrotik with Cisco VLAN made easy ~!~ You can create a VLAN by assigning a number to it you can delete VLANs as well as moving them from the active operational state to the suspended operational state. The default VLAN (VLAN1) uses only default values, and you cannot create, delete, or suspend activity in the default VLAN.
All configured ports belong to the default VLAN when you first bring up the switch. VLANs are numbered from 1 to 4094 (extended range). VLANs have the same attributes as physical LANs, but you can group end stations even if they are not physically connected to the same switch. Technology: Enterprise Switching Area: VLAN Vendor: Cisco Software: 12.X, 15.X Platform: Catalyst SwitchesĪ VLAN is a group of end stations in a switched network that is logically segmented by function, team or application, regardless to the physical locations of the users.
