GSLB domain-level affinity
1
Command line interface
Users will now be able to configure domain-level affinity groups in addition to the global affinity
definitions. The new command line interface for the domain-level affinity feature is described
below.
Creating a domain-level affinity group
To create a domain-level affinity group, use the following commands.
ServerIronADX(config)#gslb affinity-group 1
ServerIronADX(config-gslb-affinity-group-1)#
Syntax: [no] gslb affinity-group <group-number>
• <group-number>—specifies the group number
Specifying affinities definitions for the domain-level affinity group
To specify the affinities for the domain-level affinity group, use the following commands.
ServerIronADX(config)#gslb affinity-group 1
ServerIronADX(config-gslb-affinity-group-1)# prefer 1.1.1.102 for 1.1.1.0/24
ServerIronADX(config-gslb-affinity-group-1)# prefer 2.1.1.1 for 2.1.0.0/16
Syntax: [no] prefer <site-name> <si-name> | <si-ip-addr> for <ip-addr> <ip-mask> |
<ip-addr>/<prefix-length>
Configuring an affinity for prefix 0.0.0.0/0
To configure an affinity for a ServerIron ADX for prefix 0.0.0.0/0, use the following commands.
ServerIronADX(config)#gslb affinity-group 1
ServerIronADX(config-gslb-affinity-group-1)# prefer 1.1.1.102 for 1.1.1.0/24
ServerIronADX(config-gslb-affinity-group-1)# prefer 2.1.1.102 for 0.0.0.0/0
When this group is associated with a domain, all clients from subnet 1.1.1.0/24 querying for this
domain are directed to ServerIron ADX 1.1.1.102. All other client subnets querying for this domain
are directed to ServerIron ADX 2.1.1.102.
Associating the domain-level group with a domain
To associate a domain-level affinity group with a domain, use the following commands.
ServerIronADX(config)# gslb dns zone gslb.com
ServerIronADX(config-gslb-dns-gslb.com)# host www http
ServerIronADX(config-gslb-dns-gslb.com)# host www affinity-group 1
Syntax: host-info <host-name> affinity-group <group-number>
• The <host-name> parameter specifies the host name.
• The <group-number> parameter is the group number of the domain-level affinity group being
associated with this domain
NOTE
You have to configure the domain-level affinity group before you can associate it with the domain.
