arpio-config:renumber:
Map a private network CIDR block to a different IPv4 CIDR block in the recovery environment.
arpio-config:renumber:<cidr-block>[@<rec-subscription>|<rec-region>]=<rec-cidr-block>
<cidr-block>
An IPv4 CIDR block in the tagged Virtual Network that should be created with a different network address in the recovery environment.
The <cidr-block> value should match one of the CIDR blocks assigned to the tagged Virtual Network. Using a block that is larger or smaller than the Virtual Network's CIDR block may cause problems when resource addresses are configured in the recovery environment.
| in the CIDR block in place of /, which is not allowed in Azure tag names. You must also use | to separate the subscription and region if specified. In the recovery CIDR (tag value) you may use either | or the standard /.<rec-subscription>
An optional part of the tag name that causes Arpio to use this configuration tag only when the Virtual Network is being recovered in the specified recovery subscription and region. Give the subscription ID in lowercase.
If you specify a recovery subscription in the tag name, you must also specify a recovery region.
<rec-region>
An optional part of the tag name that causes Arpio to use this configuration tag only when the Virtual Network is being recovered in the specified recovery subscription and region.
If you specify a recovery region in the tag name, you must also specify a recovery subscription.
<rec-cidr-block>
The IPv4 CIDR block to use when recovering the tagged Virtual Network's <cidr-block>. The CIDR block must have the same prefix length (network size) as <cidr-block>, and it should not overlap with any other CIDR block that will be assigned to the Virtual Network in the recovery environment.
Supported Resources
- Virtual Network
Description
You can use the arpio-config:renumber: configuration tag to map a Virtual Network's CIDR block to a different CIDR block in the recovery environment. You can define multiple tags if your Virtual Network uses multiple IP ranges.
When you use this tag, Arpio automatically translates network addresses of resources using the Virtual Network (such as subnets, virtual machines, load balancers) into the specified recovery CIDR block when it recovers those resources.
This tag is useful when you want to maintain persistent VPN connections to both your primary and recovery environments, but do not want to introduce complex routing rules or network address translation to handle duplicate private address spaces.
You can use this tag on one or more networks in a Virtual Network. When you set this tag, you can format the tag name to include a specific recovery subscription and region, or leave those parts out of the name so the renumbering happens in all recovery environments.
Arpio uses the most specific tag when recovering Virtual Network networks. If there's a tag for a network that specifies a recovery subscription and region, that tag's value will be used for that recovery environment. The other tag will be used for other recovery environments.
