Hi everyone
I've implemented the Babel RTT extension specified in
draft-ietf-babel-rtt-extension in Bird. I've tested that it talks to
babeld on a single link and that the two implementations agree on each
others' (smoothed) RTT values. However, I'd like to subject the code to
some more tortured testing before submitting it to upstream Bird. So I'm
sending this note as a request for testing.
The code currently lives here:
https://github.com/tohojo/bird/tree/babel-rtt-01
To compile it, do:
git clone -b babel-rtt-01 https://github.com/tohojo/bird
cd bird && autoreconf && ./configure && make
To run it, create a config file enabling the RTT extension; the simplest
way to do this is to set the interface type to 'tunnel'. A sample
minimal config is included below (just change the interface name from
"veth0"). Save this and run Bird in the foreground in debug mode like:
./bird -c sample.conf -d
Any feedback (successes or failures) greatly appreciated!
