MTCRE-Module-01: Static Routing

-

 

OBJECTIVES- 

  • Static Routing/Default Route
  • ECMP(Equal Cost Multi-Path)
  • How to force gateway over specific interface.
  • Gateway reachability check and route distance.
  • Routing mark and route policy.
  • Recursive next-hop and scope/target-scope usages.

1. Static Routing in MikroTik RouterOS


Static routing in MikroTik means manually defining the path that packets should use to reach a destination network. It is mainly used in:

  • Enterprise networks
  • ISP environments
  • Multi-WAN setups
  • VPN routing
  • Traffic engineering
  • Backup internet links

MikroTik routing configuration is done mainly from: /ip route

"or"

BASIC STATIC ROUTING CONFIGURATION: TOPOLOGY INFO -

LAN NETWORK: 

10.0.100.0/24

ROUTER GATEWAY: 

10.0.100.254

ISP GATEWAY: 

192.168.68.1

WAN IP :

192.168.68.100/24



Example for Basic Static Route (GUI/TERMINAL):

Step-01: Click on "IP" => Routes => Click on "NEW", and fill the following field for basic static/default routes=> Apply + OK.


Step-02: Ultimately, Check the Route List, Here - [A: Active, S:Static]




2. ECMP (Equal Cost Multi-Path)

To forward packets toward a single destination with the multiple paths with the equal metrics instead of selecting one single best path, its called the ECMP. Its perform basic two purposes of the entire network-
  • Load Balancing for smooth distribution of the packets among the multiple paths, to ensure the best performance, high availability, and scalability of the entire network.
  • Failover for continuous connection of the entire network, and ensure the minimal downtime as redundant system with the different metrics.

Example: The following steps of ECMP configuration for unequal WAN connection(WAN1:WAN2=2:1) -
  1. Renaming MikroTik interface name
  2. Assigning WAN and LAN IP
  3. Assigning DNS IP
  4. NAT configuration and
  5. Routing configuration
  6. ECMP Rule in Firewall.

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...
