Hi Juan,

yes, you need to do this in the cfg. You can use a static setup, like having 
three different failure_routes that goes over three domains. Another option 
is to load the failure routes from the DB, then you would need only one 
failure route, but need to setup this in the DB. Take a look to the example 
1.18 in the cr README about how to use the cr_next_domain function.

Cheers,

Henning
