Project Overview & Architecture

Complete engineering blueprint for deploying dual-ISP load balancing with MikroTik RouterOS PCC, OSPF dynamic failover, and strict VLAN isolation.
Case Study

Challenge, Process & Outcome

The Challenge

Frequent ISP fiber cuts and single point of failure caused critical call center and office downtime.

The Solution

Deployed dual-WAN PCC load distribution with automated VRRP failover and dedicated management VLANs.

Process & Methodology

Audited multi-homed ISP feeds, configured PCC load balancing algorithms, and tuned dynamic ping watchdogs.

Measurable Impact

Achieved 99.99% network uptime with sub-second automated failover and zero packet loss.
