Linux Routing

[monday90]

I know Linux is easily configurable as a basic router. But does anyone know how feasable it is to configure protocols such as OSPF and BGP on a Linux box? At a push even MPLS? The aim here is to put around 40 "old" machines to use in a training environment without the expense of purchasing a load of very pricey cisco routers. The "old" machines are typically p4's with 256mb ram so plenty of life left there.

You will find lots of info searching for "opensource routing daemon."

One is Quagga.

Quagga is a routing software package that provides TCP/IP based routing services with routing protocols support such as RIPv1, RIPv2, RIPng, OSPFv2, OSPFv3, BGP-4, and BGP-4+ (see section Supported RFCs). Quagga also supports special BGP Route Reflector and Route Server behavior. In addition to traditional IPv4 routing protocols, Quagga also supports IPv6 routing protocols. With SNMP daemon which supports SMUX protocol, Quagga provides routing protocol MIBs (see section SNMP Support).

Quagga uses an advanced software architecture to provide you with a high quality, multi server routing engine. Quagga has an interactive user interface for each routing protocol and supports common client commands. Due to this design, you can add new protocol daemons to Quagga easily. You can use Quagga library as your program's client user interface.
