Global Server Load Balancing
7. Define the default gateway. The router at the edge of the site acts as the default gateway to the
Internet. The default gateway address should be on the same subnet as the IP interface 101,
which points to the Internet. To configure the default gateway for this example, enter the
following commands:
>> IP Interface 101# /cfg/l3/gw 1
>> Default gateway 1# addr 200.200.200.101
>> Default gateway 1# ena
8. Apply and save the configuration.
>> # apply
>> # save
9. Configure the master DNS server to recognize the local GSLB Alteon as the authoritative name
server for the hosted services.
Determine the domain name that will be distributed to both sites and the hostname for each
distributed service. In this example, the San Jose DNS server is configured to recognize
200.200.200.1 (the IP interface of the San Jose GSLB Alteon) as the authoritative name server
for "www.gslb.example.com."
To configure the San Jose Alteon for standard SLB
1. Assign an IP address to each of the real servers in the local San Jose server pool.
The real servers in any real server group must have an IP route to Alteon that will perform the
SLB functions. This is most easily accomplished by placing Alteons and servers on the same IP
subnet, although advanced routing techniques can be used as long as they do not violate the
topology rules.
For this example, the host real servers have IP addresses on the same IP subnet.
2. 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 10
>> Real server 10# rip 200.2.2.10
>> Real server 10# ena
>> Real server 10# /cfg/slb/real 20
>> Real server 20# rip 200.2.2.20
>> Real server 20# ena
3. On the San Jose Alteon, define a real server group.
Combine the real servers into one service group and set the necessary health checking
parameters. 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# /cfg/slb/group 1
>> Real server group 1# add 10
>> Real server group 1# add 20
