Hey all-
Trying to build the following network as shown in the attachment, and have a question on how to setup controller discovery.
After looking in the 6.1 UG, I know that this is deployment option 2, where the AP's are seperated by a L3 device from the controllers. My first thought was to simply put an ip helper address with the VRRP IP of the controllers so that the controllers could send a local IP address to the AP's and the GRE tunnel could be built, but then it occured to me that the AP will still need a local network address so that it knows where it's next hop is.
I can't find explicit info on this, so I'm wondering how it needs to be setup to:
1. Allow the AP's on a seperate L3 subnet than the controllers
2. Use DHCP to find both their DG and the controller's IP (something else recommended)?
3. Ensure that the GRE tunnel can be formed between the AP's IP address and the VRRP address. (Pretty sure the answer is yes).
I know this is a covered scenario, just want to make sure I've got my ducks in a row here. Thanks all!
