RAP in HA setup

Hi,

 

just wanted to doublecheck as i did not find it in the 'Aruba Remote Access Point Solution Guide'.  

 

ArubaOS 8.6 and two mc's in HA.  No vrrp.

 

I see a rap (on the public internet) connected to one mc but the standby ip is 0.0.0.0.

If i shutdown this controller, will the rap connect to the second mc?

 

In 6.5 this only worked with vrrp.  Not sure with aos 8...

Each mc has it's own public ip.  I configured the LMS and will test a failover (once financial closure has finished).

Re: RAP in HA setup

The standby IP is only used with clustering, so the 0.0.0.0 is expected.

 

Do your controllers have public reachable IPs?

Or can the controllers be reached by NAT?

Do you have a unique IP/nat per controller?

How do you point your RAPs to those IPs?

 

If you have a single public IP, the use of VRRP can help here if you point the NAT to the VRRP. If it points to a single controller IP, if that controller becomes unavailable there is no way for the RAP to reach the controller.

If you have multiple public IPs, you can either use LMS/Backup-LMS as suggested before or use round-robin DNS by pointing the RAP to a DNS name that has both (or all) public IPs of your controllers. When using LMS, make sure you point to the public IPs.
