Intel manual Delegate authority to the 7190s

Step 7. Configure the Secondary 7190.

Configuration of secondary 7190s is very easy. First you use the Boot Monitor to configure the hardware and network information (see the chapter on Installation, Startup and Configuration). Then you choose “Become a Secondary” in the Quick Start Wizard when it comes up. Enter the IP address of the primary 7190 (10.1.1.1). In a matter of seconds after issuing the command the secondary has a copy of the configuration from the primary. Subsequent commit commands automatically transfer the configuration to every attached secondary. This automatic process of transferring (copying) a configuration from primary to secondary 7190s is called Global Sync.

Step 8. Delegate authority to the 7190s.

The primary name sever responsible for the mstd-ex.com domain needs to be modified. The modifications vary depending on the type and version of the DNS server used. For this example it is assumed that a Bind server is being used.

At a Bind DNS server, add the following lines to the database file for the mstd-ex.com domain. Typically this file would be called something like “db.mstd-ex”.

geo.mstd-ex.com.	IN NS	nswc.mstd-ex.com.
geo.mstd-ex.com.	IN NS	nsec.mstd-ex.com.
nswc.mstd-ex.com.	IN A	10.1.1.1
nsec.mstd-ex.com.	IN A	10.1.2.1

www.mstd-ex.com. CNAME www.geo.mstd-ex.com.

Step 9. Verify the configuration and network operation.

There are many tools available to accomplish this step. The simplest is to ping www.mstd-ex.com. Since we have initially configured for Weighted Round Robin (with a weight of 1) we expect to ping 10.2.1.100. After waiting at least 60 seconds (the default Time To Live for a 7190 response) perform another ping. This time it should ping 10.2.2.100. Performing this a third time should result in the first service being pinged again.
