Task 2: Configure the California Switch for Standard SLB
1.
Assign an IP address to each of the real servers in the local California server pool.
The real servers in any real server group must have an IP route to the switch that will perform
the SLB functions. This is most easily accomplished by placing the switches and servers on the
same IP subnet, although advanced routing techniques can be used as long as they do not vio-
late the topology rules outlined in
For this example, the host real servers have IP addresses on the same IP subnet:
Table 12-1 GSLB Example: California Real Server IP Addresses
Real Server
Server A
Server B
2.
On the California switch, define each local real server.
For each local real server, you must assign a real server number, specify its actual IP address,
and enable the real server. For example:
>> Default gateway 1# /cfg/slb/real 1
>> Real server 1# rip 200.200.200.2
>> Real server 1# ena
>> Real server 1# ../real 2
>> Real server 2# rip 200.200.200.3
>> Real server 2# ena
3.
On the California switch, define a real server group.
Combine the real servers into one service group and set the necessary health checking parame-
ters. In this example, HTTP health checking is used to ensure that Web content is being served.
If the index.html file is not accessible on a real server during health checks, the real server
will be marked as down.
>> Real server 2# ../group 1
>> Real server group 1# add 1
>> Real server group 1# add 2
>> Real server group 1# health http
>> Real server group 1# content index.html (Set URL content for health checks)
