Virtual Links
Lesson 6 of 7
Introduction
In this lesson, we will configure virtual links in OSPF to connect disconnected areas through a transit area. This is crucial in larger networks where areas may not be directly connected, ensuring that OSPF can maintain a complete routing table and provide efficient path selection.
Quick Recap
In our previous lessons, we discussed the OSPF topology, which included multiple areas. For this lesson, we will focus on connecting Area 1 and Area 3 through Area 2 using virtual links. The devices involved are Router A, Router B, and Router C, with the following IP addresses:
- Router A (Area 1): 192.168.1.1
- Router B (Area 2): 192.168.2.1
- Router C (Area 3): 192.168.3.1
