SYNTAX
Configure the topology component within the gtm module using the syntax
shown in the following sections.

delete topology
[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
