Hi All
I currently have an Anchor controller (Cisco 5520) with AirOS version 8.5.151.0 and i am going to deploy a Cisco 9804 as a Foreign controller. Can anyone suggest do i need to upgrade the AirOS on my Anchor to the guest EOIP tunnel to be formed between the Cisco 9804 (foreign) and Cisco 5520 (Anchor). If yes to which version ?
Thanks in advance !
