5. The local DNS server sends the GSLB DNS response to the querying client.
6. The US IPv6 client initiates communication with the selected VIP. Application traffic flows
directly between the IPv6 client and the IPv6 VIP at GSLB Site 10.
Basic GSLB for IPv6 configuration
Basic configuration tasks include the configuration of the GSLB Brocade Virtual ADX and the site
Brocade Virtual ADXs to support GSLB of IPv6 addresses. Tasks include the configuration of a VIP
for the ADNS, the enabling and configuration of DNS cache proxy mode with override lists, and the
definition of zones and sites on the GSLB Brocade Virtual ADX. Also, the GSLB protocol must be
enabled on the site Brocade Virtual ADXs.
The features shown in
describe the configuration parameters required for a basic GSLB
for IPv6 configuration.
Configuring the GSLB controller
The GSLB Brocade Virtual ADX supports global server load balancing in DNS cache proxy with DNS
override mode. In this mode, the GSLB controller responds directly to DNS queries with the “best”
address, from a configured list of addresses, at the top of the DNS response.
When you enable the DNS override feature, you need to configure an IP list for the required
domains. The Brocade Virtual ADX performs health checks on the IP addresses configured for the
domains and directly responds to client queries by using the GSLB policy to select the best IP
address from the IP list configured for the requested domain.
NOTE
Although you do not need a real DNS server when you combine DNS cache proxy with DNS override,
you still need to configure a virtual IP address for the DNS server. Clients send queries to the virtual
IP address.
