freeRouter source tree
freeRouter is a router stack which can export the computed tables to external dataplanes
yet another routing/forwarding network stack made by highly skilled network/electrical/engineers
more about the project at www.freertr.org
you can find the same source tree at various locations, normally all should be the same:
- http://src.freertr.org/src/
- http://sources.freertr.org/
- http://codeberg.org/mc36/freeRtr
- http://bitbucket.org/mc361/freertr
- http://gitlab.com/mc36mc/freeRtr
- http://github.com/mc36/freeRtr
part of the subdirectories under misc/ are somewhere else too:
- p4bf at http://bitbucket.software.geant.org/projects/RARE/repos/rare/browse
- p4lang at http://github.com/rare-freertr/RARE-bmv2
dependencies
you'll need an up to date debian sid with a jdk installed
for natives, you'll need clang, dpdk, libpcap, libbpf, libxdp, liburing, libmnl and libcrypto
directory structure
the following directories could be found here:
- src contains the main sources
- cfg contains the self tests
- misc contains some smaller subprojects, see below
the following directories will appear here:
- img vm images used for interop and dataplane testing
- binDwn packages used for demo vm creation
- binDsk rootfs used for demo vm creation
- binMnt rootfs mounted for demo vm creation
- binImg outcome of demo vm creation
- binOut output of compilation
- binTmp output of testing

getting started
there is no build system in use, but you'll find shell scripts:
- d.sh to clean up
- c.sh to compile
- r.sh to run
- t.sh to selftest
as a first start to get your routers up, do the following:
- cd src
- ./c.sh
- ./tw.sh rout-bgp001
- telnet 127.0.0.1 20001
- telnet 127.0.0.1 20002
- telnet 127.0.0.1 20003
- telnet 127.0.0.1 20004
contributing
to start coding on the project, take a look on the following:
- grep me-the in the sources to see how to add a show command
- grep ifcHdlc to see how to add a new interface encapsulation
- take a look on rtrDownload to see an exmaple routing protocol
- find out how to add a new game to the command line interface
- try to solve a puzzle from the todo.txt in the source tree
- in most of the folders there is a class to extend or implment
- your eyes will bleed because of the mix of c, p4 and java
feel free to reach us on the mailing lists with your patches, ideas, feature requests, etc
