I'm setting up a new Aruba environment on AOS8 and I'm just wanting a second/third/fourth set of eyes to verify that I'm doing it correctly.
I have a single MM vm. I have 2 physical MC's..each in a different data center geographically. Each MC will be primary for AP's local to it and backup for AP's local to the other MC.
I've setup 2 VRRP instances:
vlan1 - primary on MC1 and secondary on MC2 - dnsentry1 - Primary vlan for MC1
vlan2 - primary on MC2 and secondary on MC1 - dnsentry2 - Primary vlan for MC2
I'm setting up separate DNS entries for each VRRP address and the AP's will have a primary VRRP dns entry as their method of controller contact with LMS backup IP address pointing to the controllers IP (in case dns breaks).
I have configured the 2 controllers with an HA group and added in each physical controller IP (2 per controller) to the HA group as DUAL role so that they can serve as active and standby for some AP's.
I did not configure anything under "Master Redundancy" as I'm not sure if that's only for an active/standby setup? And I figure the MM will handle sync'ing of local DB accounts, etc.
So now my question is clustering. The controllers are in separate data centers, but I do have a L2 connection between the data centers and I've added both vlans to that trunk.
How does clustering fit into the mix? I'm a little confused how all the redundant configurations fit together.
My thought is that clients connecting to AP1 terminating on MC1 will be on vlan 1. If MC1 fails and MC2 takes over, then AP1 will be terminating that client on MC2. Since MC2 has a L2 connection back to the core in the MC1 data center, routing shouldn't be a problem. Of course latency will probably be an issue.
Any help is appreciated. Thanks!
