This lesson is part of the Network Analysis with Batfish Course.
Within this lesson, we will cover:
- How to centrally analyze your networks routing tables.
- How to perform filtering to validate loopback advertisement via OSPF.
Introduction to Routing Table Analysis
Let’s now turn our attention to routing table analysis via the bfq.routes() question. This question allows you to view every single route within your network topology. As shown below:
