Built-intools plus a few software, which you can install from ports collection, will help youset up a reliable network router that supports all the important protocols that youneed in a modern network. All major routing protocols including RIPv2, OSPF, andBGP are supported using the routed, openbgpd, and openospfd utilities. Thereis also an excellent routing toolkit called Quagga in the ports tree that supportsthese protocols, and also offers a CLI interface and a Juniper Networks JUNOS likeconfiguration syntax. Using some advanced network interface cards (those whichsupport hardware offloading), you can set up a high throughput routing platform foryour network.[ 173 ]
