A similar transition is emerging in the networking space, with network control logic shifting from proprietary hardware-based platforms to open source software-based platforms. CloudRouter is a software-based router distribution designed to run on physical, virtual and cloud environments, supporting software-defined networking infrastructure. It includes the features of traditional hardware routers, as well as support for emerging technologies such as containers and software-defined interconnection. CloudRouter aims to facilitate migration to the cloud without giving up control over network routing and governance.",

 # Packer for Debian based GNS3 appliances
 
-## Packer Version Dependency
+## Debian
 
-Packer versions 1.6.0 or later do not accept templates
-that use the `iso_checksum_type` attribute.
-To use these newer versions, you must delete the line
-containing `iso_checksum_type` from debian.json.

-## Generate debian-cloud-init-data image
-
-debian-cloud-init-data can be generated with the following commands:
+Provisioning preserves upstream DNS through the switch to `resolvconf`.
+Cloud networking and the temporary build DNS entry are removed only after
+the appliance packages have been installed. Repository update failures abort
+the build rather than continuing with incomplete package indexes.
 
 ```

 ```
 
-## Debian CLI
+This builds both amd64 and arm64 images. To select one architecture:
 
 ```
-packer build debian.json
+packer build -only=amd64 debian.json
+packer build -only=arm64 debian.json
 ```
 
-## Debian-11 CLI
+The arm64 builder uses Debian's arm64 cloud image, `qemu-system-aarch64`,
+and software emulation. It requires aarch64 UEFI firmware, defaulting to
+`/usr/share/AAVMF/AAVMF_CODE.fd` and `/usr/share/AAVMF/AAVMF_VARS.fd`.
+Override `efi_firmware_code` and `efi_firmware_vars` for other firmware paths.
+Its cloud-init ISO is generated from `user-data` and `meta-data` using
+`xorriso` or another Packer-supported ISO creation tool.
 
-```
-packer build -var-file=debian-11.json debian.json
-```
+Outputs are written to `output-amd64` and `output-arm64`. After the build,
+each disk is renamed using the installed Debian point release from
+`/etc/debian_version` and the architecture, for example
+`debian-13.2-amd64.qcow2`. Setup scripts can write an application version to
+`/tmp/packer-app-version` to include it as well; `bird2.sh` records the BIRD
+version, producing e.g. `debian-13.2-bird2-2.17.1-arm64.qcow2`. Run Packer
+from this directory, since the version file is downloaded to the current
+directory before renaming.
