MTCNA Class 03: Basic Networking Configurations(DHCP, Bridge, and Routing)

-

 

Objectives-

  1. Mikrotik Interface Configuration and LAN Setup.

  2. Bridge Configuration and IP Setup.

  3. DHCP Configuration for Network Addressing.

  4. IP Routing Basics and Static Routes.


Mikrotik Interface Configuration and LAN Setup

  1. After login by winbox, Interfaces -> ether1, Comment as WAN

  2. ether7 & ether8, comment as LAN



Bridge Configuration and IP Setup

  1. Click on the Bridge button from the left Navigation bar -> Press (+) sign for new -> Fill up General information -> Click on Apply & OK. Comment as Bridge-LAN for LAN Ethernet Ports.


  1. Add Selected Ethernet Ports for this created Bridge, i.e, ether7 & ether8.


  1. Assign the IP addresses for WAN and LAN interfaces




DHCP Configuration for Network Addressing

  1. Create a Pool for the DHCP Server and Fill up the following steps to do this.

  1. Click on the IP option -> Click on DHCP Server -> Click on DHCP tab -> press (+) sign or Click on DHCP setup Option and go for next steps.

  1. Finally Fill up all of the marked fields and Click on Apply & OK for creating DHCP Server. 



IP Routing Basics and Static Routes

  1. By Default Some Routes will be created on the Routing Table. For example, directly connected cables.



Static Routing Configuration 

Scenario: 

Since Head Office and Branch Office are already point-to-point connected and use static routes between each MikroTik Routers, solution for this diagram is -

  1. Basic Network Configure, i.e. access to MikroTik Routers, IP Address assigned to each interfaces for both, Assign DNS, bridges if needed.

  2. Static Routing Configuration between two routers and so that may communicate with every sub-network. 

For Head Office Router -

/ip route

add disabled=no dst-address=20.0.0.0/24 gateway=9.10.11.2 routing-table=main \

    suppress-hw-offload=no



For Branch Office Router -

/ip route

add disabled=no distance=1 dst-address=10.0.0.0/24 gateway=9.10.11.1 \

    pref-src="" routing-table=main scope=30 suppress-hw-offload=no \

    target-scope=10

CCNA Class 10: Introduction of Routed & Routing Protocols and Configuration

Introduction of Routing Protocols Routing Fundamental Routing is the process of forwarding data packets from their source to their destination across interconnected networks. It is a critical function in both small-local area networks (LANs) and large-scale wide-area networks (WANs), including the Internet. There are two types of data packets - Routed Protocols and Routing Protocols.   Fig: Basic Routing Key Concepts in Routing Router: A router is a networking device responsible for forwarding data packets between networks based on their IP addresses. It operates at the network layer (Layer 3) of the OSI model. Routing Table: A database stored in a router that contains information about network destinations and how to reach them. Consists of: Destination network Next hop: The next router or device to which the packet should be sent. Metric: A value indicating the "Cost" of reaching a destination (hop count, bandwidth, latency, reliability, load). Interface: The router i...

CCNA Class 11: Distance vector Routing Protocol (RIPv1 & RIPv2) Configuration

DISTANCE VECTOR ROUTING PROTOCOL RIP is known as Distance Vector Routing Protocol. Here Distance means number of hop counts which is calculated by Router to reach traffic source to destination and Vector means direction. In a word, RIP - to choose the least path by calculating metric value from the entire network direction while travelling traffic from source to destination. Here the scenario, when the traffic travels from R1 to destination subnet X via the upper path (R1=>R2....R8=>Subnet-X) of Network, It takes the Metric 4 value. Or, the metric will be 3 while traveling R1 to Destination Subnet X via the middle path (R1=> R5...R8=>Subnet-X) of the network and Vice versa. How to RIP Work - RIP is a distance vector protocol that exchanges routing information between routers periodically. Each router maintains a routing table that contains the next hop and the hop count for each destination network. Every 30 seconds, the router sends its entire routing table to its dir...
