The MRT Project is a monolithic multithreaded routing engine (MRTd) that was developed under a research grant at the University of Michigan. It contains multiprotocol IPv4/IPv6 routing daemons and accompanying analysis and simulation tools. The following list presents some useful details about the software:
Version? MRT 2.2.2a, a partnership between the University of Michigan and Merit Network
Architecture? Monolithic routing engine
MRT supports BGP4/4+, RIPng, RIPv2, DVMRP, and PIM-DM. The tool uses Cisco IOS Software-like CLI syntax.
To get a working MRTd system, follow these steps:
5674/tcp # MRT Routing Daemon
Although it is no longer actively maintained, the MRT package is mature and scalable. It is used in some labs in combination with GateD and Zebra/Quagga.
