Most all modern routers now support dual-protocol routing protocols. In a previous post I wrote about how you can configure a Cisco IOS router for use with OSPFv3.

Many dynamic routing protocols are being used, but most organizations rely on two for their internal routing of IP traffic: OSPF and Cisco Systems’ proprietary Enhanced Interior Gateway Routing ...

Loki allows auditing layer 3 routing protocols by abusing and highlighting configuration weaknesses. I love new security testing tools.

A dynamic routing protocol like OSPF can require significant resources from the router to calculate the shortest path across the network when there are many routers.
