Task 6: Configure the Denver Site for GSLB
Following the same procedure described for California (see
“Task 3: Configure the California
), configure the Denver site as follows:
1.
On the Denver switch, define each remote site.
When you start configuring at the Denver site, Denver is local and California is remote. Add
and enable the remote switch’s IP address interface. In this example, there is only one remote
site: California, with an IP interface address of 200.200.200.100. The following commands are
used:
Each additional remote site would be configured in the same manner. You can enable up to 64
remote sites with a total aggregate of 2048 service/site combinations.
2.
On the Denver switch, assign each remote distributed service to a local virtual server.
In this step, the local Denver site is configured to recognize the services offered at the remote
California site. As before, configure one real server entry on the Denver switch for each virtual
server located at each remote site. Since there is only one remote site (California) with only
one virtual server, only one more local real server entry is needed at the Denver site.
The new real server entry is configured with the IP address of the remote virtual server, rather
than the usual IP address of a local physical server. Do not confuse this value with the IP inter-
face address on the remote switch.
Also, the remote parameter is enabled, and the real server entry is added to the real server
group under the local virtual server for the intended service. Finally, since the real server health
checks are headed across the Internet, the health-checking interval should be increased to 30 or
60 seconds to avoid generating excess traffic.
