You can bind a wildcard DNS domain to a GSLB virtual server. Users accessing the applications behind a wildcard domain are routed to the best optimal data center, which hosts those applications. The wildcard domain handles requests for non-existent domains and subdomains. For more information about wildcard domains, see Supporting wildcard DNS domains. For information about DNS zones, see Configure a DNS zone.

To configure GSLB for a wildcard domain, you must first configure the basic GSLB setup. For details on how to configure a basic GSLB setup, see Configuring GSLB Entities Individually.

To configure a GSLB setup for wildcard domain by using the CLI

Perform the following steps to configure a GSLB setup for wildcard domain:

Create the GSLB sites.

add gslb site site1 10.0.1.10
add gslb site site2 20.0.1.10

Add the GSLB services for each site participating in the GSLB setup.

add gslb service svc1 -sitename site1 10.0.1.10  http 80
add gslb service svc2 -sitename site1 10.0.1.10  http 80
add gslb service svc3 -sitename site2 20.0.1.10  http 80
add gslb service svc4 -sitename site2 20.0.1.10  http 80

Add the GSLB virtual server that references a service being used in the GSLB setup.
```
add gslb vserver gslb_vs http

```

Add an ADNS service that listens to the DNS queries.

add service adns_udp 10.14.39.21 ADNS 53

Bind the GSLB services to the GSLB virtual server.

bind gslb vserver gslb_vs -service svc1
bind gslb vserver gslb_vs -service svc2
bind gslb vserver gslb_vs -service svc3
bind gslb vserver gslb_vs -service svc4
