Hi gurus,
I have to implement a network which consists of three buildings, each one in a different VLAN. I will go for Instant, with three Instant clusters, managed by AirWave and authentication with ClearPass captive portal. There will be the same guest SSID in the three buildings.
I understand I could implement L3 mobility between the clusters and the clients could roam between the buildings without the need for authenticating again. But the problem is there is no coverage between the buildings, so if a client moves from one building to another it will loose the connection for a few minutes. Because of this, I think if one client is already authenticated in one building, and moves to another one, because the connection will drop there will not be L3 roaming, and then when the client try to connect to the same guest SSID it will get a new IP address, and then will need to authenticate again.
Am I correct on this? Will MAC caching in ClearPass solve this?
Regards,
Julián
