Netscaler GSLB's active and standby data center solution
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.
