bmx6

Recently I find a little loop in my network:

• Node A announces 0.0.0.0/0 and looks for 10.0.0.0/8
• Node B announces 10.0.0.0/8 and looks for 0.0.0.0/0
• Node C is looking for 10.0.0.0/8 and 0.0.0.0/0

Then Node C wants to connect with 10.1.2.3 which is out of the mesh cloud.

1. It will send the packets to B, because it is announcing 10/8 and it is smaller than 0/0
2. But when B gets the packet it sends it to A because it is announcing 0/0 and bmx6 table has more preference than the default one
3. When A gets the packet it sends it back to B because it has select B for gateway of 10/8
4. And the loop starts...

I'm not sure if bmx6 would prevent these kind of scenarios, but I wanted to leave this experience here
