Installing and Configuring MikroTik in a Virtualised

Hardware Environment

Trainer: Tom SmythClass: 13/06/2007

Virtualised MikroTik




Objectives●

Understand What is Virtualisation● Receive a high-level overview of Vmware

Server

●

Understand the basics of Vmware VirtualNetwork Configuration

● Understand how to configure a virtual machinefor use with Router OS 2.9 & Router OS 3

● Understand how to configure a virtual machine

● Understand where Virtualisation can help

● Understand where Virtualisation can not help




What is Virtualisation?

● Abstraction of physical hardware

– The same virtual hardware is presented to theguest operating system despite the underlying

hardware of the server ● Logical division of physical hardware

– single powerful host server can be divided intomany discrete separate virtual servers.

– Each of these servers can run different operatingsystems.




What is Virtualisation?




What is Vmware Server

● Vmware server installs and runs as anapplication on top of a host Windows or Linuxoperating system.

● A thin virtualisation layer partitions the physicalserver so that multiple virtual machines can berun simultaneously on a single server.

●

Vmware Server isolates each virtual machinefrom its host and other virtual machines.

● Data does not leak across virtual machines andapplications can only communicate over

configured network connections




Increased Availability using Vmwareand VRRP




Security & Flexibility with SinglePurpose MikroTik Appliances




Creating a Virtual Test Network




Securing a Laptop with a MikroTikVirtual Router Firewall




●

Run MikroTik on incompatible hardware suchas

– Raid Controllers,

– SCSI Disks

– Custom Network hardware

● Flexibility for proactive Disaster recovery in theevent of hardware failure

● Increased hardware usage through morecomprehensive driver support (DMA) in theunderlying operating system

●

Break up individual router tasks into separatevirtual Machines. Scalabilit and Securit

The Power of Virtualisation




Virtual Machines

● A virtual machine is like a server, but instead of an electronic mother board it uses a softwaremother board.

● All configuration and data are stored as files.● All VMs are hardware independent and run on

Vmware server on any x86 physical server.

●

Can access physical host hardware resourcesthrough emulated hardware

● Are completely isolated and secure.




Increased Flexibility

● Responsive DR functionality full systems canbe easily moved from one physical server toanother, even while in operation.

●

Can be built and distributed as plug-and-playvirtual appliances (help sales and exposeproduct to new markets and new customers)




● Core of Networks – Using VRRP for increased availability

– Linux Clusters for maximum availability

– Provide an end to end MikroTik Solutions

–

Provide high performance multigigabit throughput** – Provide Multi purpose logically separate services

● Laptops (fire walling & Security)

● Marketing – Place Host server in Data Centre containing Demo Network Configuration

showing Dude & MikroTik Power and Ease of use

● Test labs – Testing Dynamic Routing Protocol Configuration

– Testing QOS policies

Virtualisation Applications




● Virtualisation is not practical in all cases arethere alternatives?

– RB1000 better applied in Distribution Networks

– Cluster 2x RB 1000s for high availability – Do you need to have scalability ?

– Do you need to add complexity ?

● Virtualisation requires good hardware tofunction – Xeon /Opteron Processors

– Multiple PCI/X busses

–

Multiple PCIExpress lanes – Memory on the host server must be of adequate capacity

Virtualisation Advice




● Virtual Processor

– Intel Pentium II or later, or AMD Athlon or later, depending on hostprocessor;

– Intel EMT64VT (experimental support)

– Single and multiprocessor per virtual machine on symmetricmultiprocessor (SMP) systems.

● Virtual Chipset

– Intel 440BX based motherboard with NS338 SIO chip and

82093AA IOAPIC

● Virtual BIOS

– PhoenixBIOS 4.0 Release 6 with VESA BIOS

– DMI/SMBIOS compliant for system management agent support

Virtual Machine Core Specifications




Virtual Machine StorageSpecifications

● Virtual Memory

– Up to 3600MB of memory per virtual machine,depending on the host system's configuration and

the amount of memory on the physical host● Virtual IDE Drives

– Up to four devices: IDE HDDs, CDROM or DVD

–

Hard disks can be virtual disks or physicaldisks.IDE virtual disks up to 950GB

– CDROM can be a physical device or an ISO imagefile




● Setup of Physical and virtual NICs

– If Firewall remove IP address from all physicalinterface on the host OS

– Minimise Virtual Adapters on the host – Setup additional Vmware Vmnets (virtual networks)

● Minimise vmnets for performance (Production boxes)

● Maximise vmnets for testing flexibility (test/training boxes)

● Disable Vmware Server Nat Service

● Disable Vmware DHCP Config Service

Vmware Server Preparationon Windows /Linux




Preparing A Vmware Server on Windows for MikroTik




Check The Memory Allocation




Note the Maximum totalamount of RAM allocated to VMs




Setting Up theVirtual Networks




Look at the summarywatch out for NAT & DHCP




Limit the amount of Host Virtual Adapters




Remove all DHCP NetworksStop DHCP Server Service




Disable NAT Service




Configure Physical/Virtual Network Connections
