A customer of ours has asked us about the protocols behind Instant APs and their virtual controller technology.
I guess it works more or less like VRRP with no preemption and the same priority for all APs for the master AP election. For control traffic, i suppose it still uses PAPI tunnels but I would like to give our customer a more precise answer. Are there any tecnhnical notes addressing virtual controller technology?
P.S. I've already seen the tech notes on the main webpage, but I'm afraid I need a bit more detail.
The virtual controller or master is elected using an election process that involves all IAPs in the group. If there is a contention, the IAP with the highest uptime will win.
There are no tunnels built for control traffic. The IAPs communicate using layer 2 broadcast and this is very lightweight.
There are additional details that can't be shared externally, but if there are specific questions or issues that the customer is concerned about, I will be happy to discuss those.
We've been capturing traffic in one of our customers network and have found out the following:
So the IAP works like the APs with the controller with bridge mode right?
