I have (2) local controllers on the same VLAN that I want to use VRRP for redundancy. I do not want to use the network switch to run the heartbeats for the vrrp master so I am wondering if there is a better way to accomplish sending the heartbeats to the backup controller.
I was thinking a crossover cable between controllers but not sure how this would be set up. Also, tried tracking and it seems to work.
I am looking for a best practice for the VRRP instance.
Requirements:
1. Both controllers need to send multicast traffic to each other to advertise availability for a single high availability address
2. Only one that has priority will answer on the HA address
3. All the access point traffic will be pointed at that controller
4. A switch must be used to deliver frames from those access points to those controllers that own the HA address.,
Long Story short:
- Do not put a cable between the controllers for a VRRP, because it is not only heartbeats that need to be delivered, access point traffic needs to be delivered from the rest of the network to that HA address. That means the controllers need to be plugged into a switch.
