MikroTik RouterBOARD Configuration

MikroTik RouterBOARD 750 Configuration

• A network-ready device connected to MikroTik RouterBOARD 750 with a correct UTP RJ45 cable requires an IPv4 address of 192.168.100.70 and a subnet mask of 255.255.255.252.
• For a successful connection, the RouterBOARD 750's valid IPv4 address would be 192.168.100.69/255.255.255.252.

Layer-3 Communication in MikroTik RouterOS

• Layer-3 communication between two hosts can be achieved by using an address subnet of /30.

Direct Communication between Computers

• Computers with IP addresses 192.168.17.15/29 and 192.168.17.20/28 cannot communicate directly without a router.

IP Packet Header

• An IP packet header contains 2 IP addresses.

Network Address

• The network address is the first address of the subnet.

Hardware Coded Address

• The hardware coded address found on an interface is a MAC Address.

Usable IP Addresses in a Subnet

• A 23-bit (255.255.254.0) subnet has 510 usable IP addresses.

ARP in IPv6

• ARP is not used in the IPv6 protocol.

SNMP Protocol

• SNMP uses UDP port 161.

ARP Reply-Only

• If ARP=reply-only is configured on an interface, it will accept all IP/MAC combinations listed in /ip arp as static entries.

Security Profile Configuration

• To use dynamic keys in a security profile for an AP, the dhcp server must be set up to provide the dynamic keys.

Client PC Configuration

• To access the Internet, the client PC's correct configuration is IP: 192.168.2.2/24, gateway: 192.168.2.1.

VLAN-ID Value

• In Router OS, the VLAN-ID value can be set from 1 to 4095.

Collisions in Ethernet Networks

• Collisions are not possible in full-duplex Ethernet networks.

Monitoring Real-Time Connections

• Real-time connections can be monitored using Firewall Connection Tracking.

Action=Redirect

• Action=redirect applies to DST-NAT rules.

Queue Configuration

• A simple queue can limit a host's download data rate to one megabit per second.

IP Address Lists

• The same IP address can be included in multiple address lists and still be used by these multiple address lists.

Static Routing Functionality

• For static routing functionality, the routing software package is required in addition to the RouterOS system package.

PCQ Configuration

• To allow 256k maximum download and upload for each client using PCQ, the correct argument values are kind=pcq pcq-limit=256000 pcq-classifier=src-address.

Loop Avoidance

• To avoid looping on a network, RSTP needs to be enabled on AP1 and AP3.

HotSpot Configuration

• To allow IP-phones to access outside networks without HotSpot authentication, /ip hotspot walled-garden ip can be used.

DHCP Server Configuration

• DHCP server can be configured on a router's interface, and Virtual AP can be used to allow clients to connect with a different PSK.

PPPoE Server Configuration

• Router A can use "/ppp secret" accounts from Router B to authenticate PPPoE customers.

OSPF Area ID

• OSPF area ID does not need to be unique within the AS.

HotSpot Setup

• The /ip hotspot setup command adds configuration for /ip dhcp-server, /ip hotspot user, and /ip hotspot walled-garden.

Wireless AP Configuration

• Station-wds mode can be used to configure WDS.

DHCP Server Options

• Implemented DHCP Server Options for DHCP-Client include DNS Server, subnet mask, and gateway.

Log Configuration

• To log web-proxy traffic, /system logging add topics=web-proxy,!debug action=disk can be used.

E1(T1) Connection Configuration

• To set up an E1(T1) connection with PPP configured, a Level 4 license is needed.

Client PC Configuration

• To access the Internet, the client PC's correct configuration is IP: 192.168.2.115/24, gateway: 192.168.2.1.

Collision Domains

• Segmenting a network with a 12-port switch creates 12 collision domains.

IOS Upgrade

• The command to upgrade an IOS on a Cisco router is copy tftp flash.

Trunking Protocol

• VLAN Trunking Protocol (VTP) and 802.1Q are used to configure trunking on a switch.

TCP/IP Protocol

• FTP, SMTP, and HTTP use TCP.

TCP/IP Stack

• The Host-to-Host layer is equivalent to the Transport layer of the OSI model.

DHCP Discover Message

• The DHCP Discover message uses UDP as the Transport layer protocol and FF:FF:FF:FF:FF:FF as a layer 2 broadcast.

IP Configuration

• DHCP is used to automate IP configuration, including IP address, subnet mask, default gateway, and DNS information.

Private IP Address

• 192.168.24.43 is a private IP address.

Proxy ARP

• Proxy ARP allows a router to respond to an ARP request that is intended for a remote host.
