Hi, Does anyone here deployed A10 AX as Link Load Balancer with GSLB inbound traffic server mode or subdomain mode? can you please share your running configuration as a reference.
FYI...LLB is an old term which A10 now calls it as Next Hop Load Distribution(NHLD) feature. See the instructions below as to how NHLD is deployed in inbound mode. FYI A10 can also support outbound mode.
When the Thunder appliance receives a client query for www.abc.com, the Thunder device responds with link VIPs 30.30.30.100 and 40.40.40.100, in round-robin fashion. If a link is down (for example, router 30.30.30.1), the Thunder appliance responds only with the up link (in this case, 40.40.40.100).
