[Babel-users] Random router ids

[Juliusz Chroboczek]

Hi,

I've just added the ``-r'' flag to the master branch of babeld, which
causes router-ids to be drawn randomly rather than derived from the MAC
address of the first interface.

By default, babeld uses a persistent router-id.  Most of the time that
works fine, but people are running babeld on nodes with no persistent
storage, which prevents babeld from storing the latest seqno at
shutdown; babeld will then use a random seqno, which may cause it to
become unreachable for up to 120 seconds after boot.

The ``-r'' flag causes babeld to use a random router id; it's not
recommended in general, but may be useful for folks who run babeld on
nodes with no persistent storage and that are being rebooted often.
