Netscaler GSLB's primary and standby data center solutions

GSLB's primary and standby data center solution ideas:

In fact, this is just a special case of multi-data center. In the multi-data center scheme, write location as:

NSGEO1.0

Context=custom

Qualifier1=ispname

Start

"192.168.1.50","192.168.1.60","IDC1"

"192.168.1.200","192.168.1.254","IDC2"

The primary and backup data centers only need to write all the LDNS addresses of customers into one entry, and the rest of the addresses are only back-ups. Location is

NSGEO1.0

Context=custom

Qualifier1=ispname

Start

"192.168.1.1","192.168.255.254","IDC1"

Only LDNS between 192.168.1.1-192.168.255.254 matches, meaning that users should normally access IDC1. If IDC1 fails catastrophically, then LDNS falls outside this range or because the IDC's VIP has gone down, DNS replies can only be other healthy IPs

The configuration is as follows:

*******************************************************************************************

IDC1

VIP

GSLB Service Note Add partner VIP

GSLB Vserver

location

Site

*******************************************************************************************

IDC2

VIP

GSLB Service Note Add partner VIP

GSLB Vserver

location

Site

DNS configuration

*****************************************************************************************************************

programme effectiveness

Normally, the user accesses IDC2. If IDC2 has service interruption, the user automatically jumps to IDC1.
