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.

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.

It prevents the router or switch from advertising routing updates through the interface where it is configured. For protocols like EIGRP and OSPF this command will prevent adjacencies from forming ...

Cisco claims that the router can reach a routing throughput of 92 terabits, or 92 trillion bits per second.
