[ldns: [identifier] [value] server: [identifier] [value] ]
DESCRIPTION
You can use the topology component to configure a topology statement. A topology statement is a set of
characteristics that identify the origin of a given name resolution request.
EXAMPLES
create topology ldns: country US server: datacenter DC1 score 30
Creates a topology statement that specifies that the Global Traffic Manager routes any traffic coming from the
United States to the datacenter named DC1. Note that the weight of this topology item for load balancing is
30.
delete topology ldns: country US server: datacenter DC1
Deletes the topology statement mentioned in the previous example.
OPTIONS
app-service
Specifies the name of the application service to which the topology belongs. The default value is none.
Note: If the strict-updates option is enabled on the application service that owns the object, you cannot
modify or delete the topology. Only the application service can modify or delete the topology.
description
User defined description.
glob Displays the items that match the glob expression. See help glob for a description of glob expression
syntax.
ldns:
Specifies the criteria that the Global Traffic Manager uses when matching requests from LDNS servers.
continent
A continent whose IP address allocation range should be used in matching topologies
country
A country whose IP address allocation range should be used in matching topologies
datacenter
A data center to be used in matching topologies
geoip-isp
An ISP whose IP Address allocation range should be used in matching topologies. Any ISP string may
be given as long as it matches the string in the GeoIP-ISP Database. Case is irrelevent.
isp An ISP whose IP address allocation range should be used in matching topologies
not Specify a region member to exclude from the region
pool A pool to be used in matching topologies
region
Another region to be used in matching topologies
state
A state whose IP address allocation range should be used in matching topologies
subnet
A subnet to be used in matching topologies
order
Specify the order number of this topology item. Should not be specified if the Longest Match option is
selected. Must be a value between 1 and the number of topology items inclusive (including any new
topology items). If an existing topology item specifies the same order number, the order numbers for
that item and all subsequent items are incremented.
regex
Displays the items that match the regular expression. The regular expression must be preceded by an at
sign (@[regular expression]) to indicate that the identifier is a regular expression. See help regex for
a description of regular expression syntax.
score
Specifies the weight of the topology item.
server:
Specifies the server to which the Global Traffic Manager routes requests.
continent
A continent whose IP address allocation range should be used as an LDNS routing destination
country
A country whose IP address allocation range should be used as an LDNS routing destination
datacenter
A data center to be used as an LDNS routing destination
geoip-isp
An ISP whose IP Address allocation range should be used in matching topologies. Any ISP string may
be given as long as it matches the string in the GeoIP-ISP Database. Case is irrelevent.
isp An ISP whose IP address allocation range should be used as an LDNS routing destination
not Specify an item to exclude from the group
pool A pool to be used as an LDNS routing destination
region
Another region to be used as an LDNS routing destination
state
A state whose IP address allocation range be used as an LDNS routing destination
subnet
A subnet to be used as an LDNS routing destination
