First, both nodes for the same interface statement should be in the
same network in order to work.
Second, you need at least 2 physical interfaces for redundancy (and
I'm not talking about bond here). You could set the 10.10.0.0/16
network on ringnumber 0 and 192.168.0.0/24 on ringnumber 1 (again,
you'd need 2 physical interfaces).
Third, ttl=1 for different subnets, how do you expect to route the packets?
Fourth, my personal favourite, secauth=on and threads=0. Set
threads=#number_of_cpus_on_the_system
