I have to loadbalance DNS requests.
I tried to start a configuration but I didn't find anything about L3-4 load balancing or maybe I didn't understand it. I only found L7 http or ftp load balancing.
I issued this :
class-map match-any L4_DNS
description "Match traffic for DNS VIP on tcp port 53"
2 match virtual-address xx.xx.xx.xx tcp eq domain
policy-map type loadbalance first-match L7_DNS_SLBPolicy
description "Load balancing Policy"
policy-map multi-match L4_DNS_SLBPolicy
loadbalance vip inservice
loadbalance policy L7_DNS_SLBPolicy
loadbalance vip icmp-reply active
loadbalance vip advertise active
I am not sure this will work...
Does anybody have an idea or a valid L3-4 loadblancing configuration for ACE ?
