ARP storm

[pekdz]

I think this code doesn't install a group table into switch for ARP packet if there is a loop, which may cause severe ARP storm when the topology contains lots of loops(e.g., FAT Tree).

Yes, that may be true, I tested it on simple multipaths. Do you have an example case?

Yes, you can use this script to generate a fat tree topology.

I think simply install/update group table for ARP packet when each loop discovered/updated will solve this problem.
