[avahi] The reflector option in networks with loops

[David Dyja]

Hello,

I'm doing some testing in a network with multiple routers and loops.

In the simplest form, I have three routers connected in a triangle running
Avahi with the "reflector" option activated.

Everything seems to be working fine, the hosts connected to the three
subnets see each other just fine and there is no packet storm due to the
loop.

My question to the developpers is why isn't there a problem? since the
reflector just forwards the multicast packets and changes the source
address the queries should loop infinitetly, right?

So is there a mechanism to stop the packet storm so it's ok to use the
reflector option in looped networks, or it should be avoided?

Kind regards,
David Dyja
