Cisco Switching/Routing :: CSS 11501 - Configuring CSS Content / Load Balancing

I would like configure a CSS content, that uses the sorry service principal in an advanced way.

I am familiar with the primary Sorry Server command and see that the CSS would send all connections to the named service that is configured as the primary Sorry Server.

What I would like to do is to configure the CSS, so that once it’s decided it’s in a “sorry” state (all the services that are configured with “add service” are down) that it load balances to a different set of services.

To explain what I’ve been trying to do in the form of configuration on the CSS, I’ve pasted some pretend config below.

Connections come into IP address 1.1.1.1, which normally get load balanced between  9.1.1.1, 9.1.1.2 and 9.1.1.3.

If 9.1.1.1, 9.1.1.2 and 9.1.1.3 are all down, the sorry service is used and the CSS starts passing traffic to 1.1.2.1, which I want it to load balance between  9.1.2.1, 9.1.2.2 and 9.1.2.3.

The order that I have applied the config, is different to the below, as I set out to configure in this order: secondary services, secondary content, sorry service, primary services, primary content.

The order of the config below is different, because I wanted it in the order that the traffic flows and the CSS won’t take the config in that order!

The wall I have ran into, is that when I try to create the service I have named “Sorry Service”, I get the following error:

%% Service IP Address conflicts with a local I/F, VIP, mg mt route.
