Routing back to clustered setup for user gateways

Hi,

 

This is regards to Aruba OS 8. The topology we are using is a pair of VMMs and a clustered setup of VMCs in a L2 cluster. We want to put the user gateways on the controllers.

 

So what I did was to do a VRRP setup between the two, but I am running into issues with the routing back to the cluster.

 

Controller #1(IP 192.168.100.2):

int vlan 100

ip address 192.168.1.2 255.255.255.0

ip helper address 10.0.0.10

operstate up

 

vrrp 100

ip address 192.168.1.1

vlan 100

no shutdown

 

Controller #2 (IP 192.168.100.3):

int vlan 100

ip address 192.168.1.3 255.255.255.0

ip helper address 10.0.0.10

operstate up

 

vrrp 100

ip address 192.168.1.1

priority 110

vlan 100

no shutdown

 

The VIP for our clustered setup is 192.168.100.1. So I created static routes on our routers pointing 192.168.1.1 to 192.168.100.1.  This has not worked. Is there something I am doing wrong? I'm struggling to find out why it's so hard to get the gateways working on AOS8. In AOS6 with master and FO, it was easy enough cause we put the .1s on each master and pointed the routes to the VIP.

 

Is pointing to the VIP for for the controller clusters the proper way to route back to the cluster? Is there something else wrong with my setup? TAC has not been that helpful in relaying Aruba's recommendation to me.

 

Thanks for any help.

Don't have the clustered controllers route your user traffic. Allow your routing infrastructure to do that.

Re: Routing back to clustered setup for user gateways

But we would like to keep the user gateways on the controllers. How can I achieve this?

 

How do I route the traffic to the cluster when the clients get load balanced between the controllers in the cluster?

Re: Routing back to clustered setup for user gateways

Hi root,

 

From my point of view, you have only two options:

 

  1. Do not use your controller as the gateway. Simply do a L2 forwarding on the controllers. 
  2. Use NAT on the controllers. 

Routing could not work, as you never know, which controller the current user anchor controller is.
