is it possible to do C9800 HA-SSO configuration via DNA-Center 2.3.3.6 for RP without RMI configuration?
Since the Redundancy Ports (RP) of the 2 WLCs will not be connected back to back as required for RP+RMI (Redundant Management Interface) but connected via L2 upstream switches in a dedicated L2 VLAN
"Configuring High Availability (HA) on the Cisco Catalyst 9800 Series Wireless Controller involves the following prerequisites:
The redundancy port of Catalyst 9800 Series Wireless Controller 1 and Catalyst 9800 Series Wireless Controller 2 are physically connected"
does this mean they need to be back to back connected?
if so, what is best approach to configure legacy HA-SSO with legacy RP via DNA-Center?
