    HN746: Going Deep on OSPF Route Filtering
    Aug 26 2024
    On today’s episode we delve into OSPF filtering. That is, how to filter routes from a device’s routing table in an OSPF environment. This is a tricky business, because OSPF requires an identical database on every device in an OSPF area. That means you can’t stop announcing a route from one OSPF router because you... Read more »

    HN744: How BackBox Helps You Mitigate CVEs for Network Devices (Sponsored)
    Aug 9 2024
    Today we explore a network automation use case for configuration compliance in the face of never-ending common vulnerabilities and exposures, or CVEs. If you can automate that compliance, you have a shot at keeping pace with the bots and attackers attempting to exploit those CVEs and breaching your network. Our guest is Rekha Shenoy, CEO...
