# Catalyst SD-WAN Lab Deployment Tool for Cisco Modeling Labs
This tool automates [Cisco Catalyst SD-WAN](https://www.cisco.com/site/us/en/solutions/networking/sdwan/index.html) lab deployment inside [Cisco Modeling Labs (CML)](https://www.cisco.com/c/en/us/products/cloud-systems-management/modeling-labs/index.html).
The tool will help you automate your CML lab deployments with SD-WAN Manager, Controllers and Validators and up to 20 SD-WAN edges. You can build as pods as your CML platform can host. Please refer to the [Limitations and scale](#limitations-and-scale) for details.
## Getting Started
### Prerequisites
Catalyst SD-WAN Lab Deployment Tool requires Linux or macOS system.
To run is on Windows, please use [Linux on Windows with WSL](/README.md#appendix---wsl-installation) or set up Linux VM/container.
Catalyst SD-WAN Lab Deployment Tool requires Python 3.9 or newer. This can be verified by pasting the following to a terminal window:
% python3 -c "import sys;assert sys.version_info>(3,9)" && echo "ALL GOOD"
If 'ALL GOOD' is printed it means Python requirements are met. If not, download and install the latest 3.x version at Python.org (https://www.python.org/downloads/).
All the Python prerequisites are automaticaly installed when you install the package. Please refer to the [Installing](#installing) section for details.
This tool requires CML 2.6 or higher.
### Installing
The recommended way to install is via pip.
Create a directory to store the virtual environment and runtime files:
mkdir csdwan
cd csdwan
Create virtual environment:
python3 -m venv venv
Activate virtual environment:
source venv/bin/activate
- Note that the prompt is updated with the virtual environment name (venv), indicating that the virtual environment is active.
Upgrade initial virtual environment packages:
pip install --upgrade pip setuptools
To install SD-WAN Lab Deployment Tool:
pip install --upgrade catalyst-sdwan-lab
Verify that SD-WAN Lab tool can run:
sdwan-lab --version
You can also use the following shortcut to run any lab task:
csdwan --version
Notes:
- The virtual environment is deactivated by typing 'deactivate' at the command prompt.
- Before running Catalyst SD-WAN Lab Deployment Tool again, make sure to activate the virtual environment back again (source venv/bin/activate).
## Usage
Simmilar to [Sastre](https://github.com/CiscoDevNet/sastre), the command line is structured as a set of base parameters, the task specification followed by task-specific parameters:
sdwan-lab <base parameters> <task> <task-specific parameters>
Base parameters define global options such as verbosity level, CML credentials, etc.
Task indicates the operation to be performed. The following tasks are currently available:
* [Setup](#setup-task): Setup CML to support Catalyst SD-WAN use cases, upload new software images, and create node and image definitions that are required to run Catalyst SD-WAN lab in the CML.
* [Deploy](#deploy-task): Deploy CML topology with two underlay networks (INET, MPLS), one Manager/Validator/Controller, and one Gateway router. Once topology boots up, configure the control components and create basic templates / configuration groups.
* [Add](#add-task): Add and automatically onboard additional SD-WAN nodes (Validators/Controllers/Edges) to existing lab.
* [Backup](#backup-task): Backup the Catalyst SD-WAN Lab runnning in CML, including the CML topology and all its nodes, SD-WAN device states and templates / configuration groups.
* [Restore](#restore-task): Restore the Catalyst SD-WAN Lab from backup, onboard and confgure control components and create basic feature templates / configuration groups. If there are any WAN Edges, automatically onboard the WAN Edges back to the SD-WAN Manager using the configuration from the backup.
* [Delete](#delete-task): Delete currently running lab from CML and remove all lab data.
* [Sign](#sign-task): Sign Certificate Signing Request (CSR) using SD-WAN Lab Deployment Tool Root CA
Task-specific parameters are provided after the task argument.

* MANAGER_USER
* MANAGER_PASSWORD
* MANAGER_MASK
* MANAGER_GATEWAY
* LAB_NAME
For any of the required arguments, user is prompted for a value if they are not provided via the environment variables or command line arguments.
The easiest way to run the tool is to provide all the lab variables in the rc file and source that file. The example file below contains all the variables required to run all the tasks.
% cat rc-example.sh
export CML_IP='10.0.0.1'
export CML_USER='user1'
export CML_PASSWORD='password123'
export MANAGER_IP='10.0.0.10'
export MANAGER_USER='sdwan'

export MANAGER_GATEWAY='10.0.0.254'
export LAB_NAME='sdwan'
% source rc-example.sh
Note that if password was not defined, the user will be prompted for a password. Also please note we recommend not to use admin user as MANAGER_USER. Instead, configure a different user name to always have a backup user. By default, the MANAGER_PASSWORD will be set for both admin user and the MANAGER_USER that you specify.
Note that MANAGER_IP can be:
- an IP address: SD-WAN Manager will be reachable over this IP address. By default the IP address should come from the same subnet as CML IP, unless custom bridge is specified during deploy task.
- a PATty port in format "pat:<outside-port>": SD-WAN Manager will be reachable over CML IP port <outside-port>. Before using this option, PATTy needs to be enabled on the CML server as per [CML documentation](https://developer.cisco.com/docs/modeling-labs/patty-tool-overview/).
### Task-specific Parameters
Task-specific parameters and options are defined after the task is provided. Each task has its own set of parameters. Check the task documentation to learn more about task-specific parameters.

Deploys basic SD-WAN topology with:\n * two underlay networks (INET, MPLS)\n * one Manager\n * one Validator\n * one Controller\n * one Gateway router that connects VPN0 subnet to INET and MPLS subnets\n3. Once topology boots up, the task configures the control plane (control components, certificates, etc.) and create basic feature templates / configuration groups that can be used for WAN Edge onboarding. It also attaches Controller to device template.\n4. At this point you can start creating your custom topology using [Add Task](#add-task) to automatically onboard additional SD-WAN nodes (Validators/Controllers/Edges).\n\nYou should run this task to deploy a new lab with control plane configured and build any WAN Edge topology you like.\n\nThis task has several task-specific parameters, including software version that you want to run on the control components.\n\n sdwan-lab deploy -h\n usage: sdwan-lab.py deploy [-h] [--manager <manager-ip>] [--mmask <manager-mask>] [--mgateway <manager-gateway>] [--muser <manager-user>] [--mpassword <manager-password>] [--bridge <custom-bridge-name>] [--dns <dns-server-ip>]\n <software-version>\n \n positional arguments:\n <software-version> Software version that will be used on SD-WAN Control Components.\n \n optional arguments:\n -h, --help show this help message and exit\n --manager <manager-ip>\n SD-WAN Manager IP address, can also be defined via MANAGER_IP environment variable. If neither is provided user is prompted for SD-WAN Manager IP.\n --mmask <manager-mask>\n Subnet mask for given SD-WAN Manager IP (e.g. /24), can also be defined via MANAGER_MASK environment variable. If neither is provided user is prompted for SD-WAN Manager subnet mask.\n --mgateway <manager-gateway>\n Gateway IP for given SD-WAN Manager IP, can also be defined via MANAGER_GATEWAY environment variable. If neither is provided user is prompted for Manager gateway IP.\n --muser <manager-user>\n SD-WAN Manager username, can also be defined via MANAGER_USER environment variable. If neither is provided user is prompted for SD-WAN Manager username.\n --mpassword <manager-password>\n SD-WAN Manager password, can also be defined via MANAGER_PASSWORD environment variable. If neither is provided user is prompted for SD-WAN Manager password.\n --lab <lab_name> Set CML Lab name, can also be defined via LAB_NAME environment variable. If not provided, default name \"sdwan<number>\" will be assigned.\n --bridge <custom-bridge-name>\n Set custom bridge for SD-WAN Manager external connection. Default is System Bridge\n --dns <dns-server-ip>\n Set custom DNS server for Internet/VPN0 transport. Default is same as CML DNS\n --retry If for some reason your script lost connectivity during SD-WAN Manager boot, you can add --retry to continue onboarding the lab that is already in CML.\n\nTime to complete the deployment task depends on:\n* SD-WAN software version\n* CML resources\n\n### Add Task\nThis task adds Catalyst SD-WAN nodes (Validators/Controllers/Edges) into existing Catalyst SD-WAN lab. This task will:\n1. Add requested number of nodes to the CML topology and boot them with cloud-init configuration\n2. Once nodes boot up, automatically onboard them to SD-WAN Manager\n3. For Controller/Edge nodes, automatically attach basic device template / configuration group\n4. For Validator nodes, automatically update Validator FQDN mapping with new IP addresses\n\nThis task has several task-specific parameters.\n\n sdwan-lab add -h\n usage: sdwan-lab.py add [-h] [--manager <manager-ip>] [--muser <manager-user>] [--mpassword <manager-password>] [--lab <lab_name>] <number-of-devices> <device-type> <software-version>\n \n positional arguments:\n <number-of-devices> Number of devices to be added.\n <device-type> Type of device/s to be added (e.g. validator, controller, edge, sdrouting).\n <software-version> Software version that will be used.\n \n optional arguments:\n -h, --help show this help message and exit\n --manager <manager-ip>\n SD-WAN Manager IP address, can also be defined via MANAGER_IP environment variable. If neither is provided user is prompted for SD-WAN Manager IP.\n --muser <manager-user>\n SD-WAN Manager username, can also be defined via MANAGER_USER environment variable.

CML doesn't natively support configuration export from Catalyst SD-WAN nodes, but this script can help you to save your Catalyst SD-WAN configuration. This task will:\n1. For Manager, Validator, Controller and WAN Edge nodes (SD-WAN and SD-Routing), create configuration backup.\n2. For non-SD-WAN nodes, export the configuration if it's supported by CML.\n3. Save the CML topology with exported configuration.\n4. Create a backup of SD-WAN Manager templates, policies and configuration groups using [Sastre](https://github.com/CiscoDevNet/sastre).\n\nThis task has several task-specific parameters, including working directory where backup is saved.\n\n % sdwan-lab back -h \n usage: sdwan-lab.py backup [-h] [--manager <manager-ip>] [--muser <manager-user>] [--mpassword <manager-password>] [--lab <lab_name>] [--workdir <directory>]\n \n optional arguments:\n -h, --help show this help message and exit\n --manager <manager-ip>\n SD-WAN Manager IP address, can also be defined via MANAGER_IP environment variable.
