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://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
you'll need an up to date debian sid with a jdk installed
for natives, you'll need clang, dpdk, libpcap, libbpf, libmnl and libcrypto
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
- native: dpdk, xdp, pcap and mnl based dataplanes
- p4bf: tofino based dataplane
- p4lang: bmv2 based dataplane
- bogon: web based bogon originator
- lookingglass: web based looking glass
- captures: script to stream captures
- sniffer: web based packet capture
- mailer: web based mail reader

- temper: web based thermostat/controller
- trackmap: web based monitoring
- voice: an answering machine
- snmp: some snmp definitions
- rfcs: rfc series renamer

- tests: some volumentric generators
- check: some check definitions
- sensor: some sensor definitions
- prometheus: some grafana definitions
- netconf: some yang definitions
- image: demo vm iso creator
- img2ova: demo vm ova creator
- service: install script
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
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
- first you should take a look at the todo.txt and the changelog.txt
- try first reordering the todo.txt if you have nothing better idea
