[Babel-users] Low-level code for tweaking routes improved

[Juliusz Chroboczek]

Hi,

I've just tweaked the low-level route-tweaking code, as suggested by
Dave and Julien in a previous thread.  Rather than trying to guess when
it is possible to insert the new route before flushing the old one, we
just try to do it, and fall-back to the other ordering if it fails.

In principle, this should reduce the number of dropped packets in
a functioning network to close to zero, as long as all nodes have their
kernels compiled with support for equal-cost multi-path.  In practice,
it might burn and crash horribly.

Please test.
