Hi, recently I used "routing" component in my mininet. I found that when the topology contained a loop it would lead to routing storm and produce a mass of packets. That is to say, "routing" don't solve the storm problem? My real testbed has a loop, I used to add static routing in nox and manually solve the arp reply packet. But I think that is not good when the topology becomes large. So can anybody help to solve the routing problem?
