| ## Dual Datacenter Topology | ||
| ## **ATD Dual Datacenter Topology** | ||
|
|
||
| The ATD Dual Data Center Topology is used in this example. The IP Network cloud is comprised of the border and core nodes in the topology. The IP Network is pre-provisioned in this example. Our focus will be building AVD data models for Site 1 and Site 2 and configuring each site to connect to an existing IP Network. | ||

| ### Vlan and Host Addressing | ||
|
|
||
| #### Site Vlans and Subnets | ||
|
|
||
| | Site | Rack | Vlan | Subnet | | ||
| |:----:|:----:|:----:|:-------------:| | ||
| | 1 | 1 | 10 | 10.10.10.0/24 | | ||
| | 1 | 2 | 20 | 10.20.20.0/24 | | ||
| | 2 | 1 | 30 | 10.30.30.0/24 | | ||
| | 2 | 2 | 40 | 10.40.40.0/24 | | ||
|
|
||
| #### Host Addressing | ||
|
|
||
| | Site | Rack | Hostname | IP Address. | | ||
| |:----:|:----:|:--------:|:---------------:| | ||
| | 1 | 1 | s1-host1 | 10.10.10.100/24 | | ||
| | 1 | 2 | s1-host2 | 10.20.20.100/24 | | ||
| | 2 | 1 | s2-host1 | 10.30.30.100/24 | | ||
| | 2 | 2 | s2-host2 | 10.40.40.100/24 | | ||
|
|
||
| **Note:** Host nodes are pre-configured with the addresses above. AVD will configure the leaf ports for the hosts. | ||
|
|
||
| ### WAN - IP Network | ||
|
|
||
| The WAN IP Network runs OSPF in Area 0.0.0.0 using /31's in the 10.0.0.0/24 address block. The Spines in each DC will peer to nodes in the cloud. | ||
|
|
||
| ## STEP #1 - Create ATD Lab | ||
|
|
||
| Create a new ATD Dual Center Lab and follow along. Ask your local account team for assistance. | ||
|
|
||
| ## STEP #2 - Fork and Clone this repo to your ATD Lab | ||
|
|
||
| From GitHub, fork this **[repo](https://github.dev/PacketAnglers/workshops-avd)** (https://github.dev/PacketAnglers/workshops-avd) to your personal GitHub account and use the Programmability IDE to clone your fork to your lab instance. | ||
|
|
||
| ``` bash | ||
| cd /home/coder/project/labfiles | ||
| git clone <your copied URL> | ||
| cd workshops-avd | ||
| ``` | ||
|
|
||
| ## STEP #3 - Update AVD to Latest Version | ||
|
|
||
| Update AVD and requirements to the latest version | ||
|
|
||
| ``` bash | ||
| ansible-galaxy collection install arista.avd arista.cvp --force | ||
| export ARISTA_AVD_DIR=$(ansible-galaxy collection list arista.avd --format yaml | head -1 | cut -d: -f1) | ||
| pip3 config set global.disable-pip-version-check true | ||
| pip3 install -r ${ARISTA_AVD_DIR}/arista/avd/requirements.txt | ||
| ``` | ||
|
|
||
| **Note:** This must be done each time you start your ATD Lab. | ||
|
|
||
| ## STEP #4 - Set Lab Password environment variable | ||
| The ATD Dual Data Center Topology above is used in this example to create an L2LS Multi-site topology below. The IP Network cloud is comprised of the border and core nodes in the ATD topology. The IP Network and hosts are pre-provisioned in this example. Our focus will be building AVD data models for Site 1 and Site 2 and configuring each site to connect to an existing IP Network. | ||
|
|
||
| The following command sets the environment variable `LABPASSPHRASE` which is used later for connecting to your lab switches and creating local user password. | ||
|
|
||
| ``` bash | ||
| export LABPASSPHRASE=`cat /home/coder/.config/code-server/config.yaml| grep "password:" | awk '{print $2}'` | ||
| ``` | ||
|
|
||
| **Note:** This must also be done each time you start your ATD Lab. | ||
|
|
||
| ## STEP #5 - Initialize IP Network Cloud environment | ||
|
|
||
| This step pushes pre-defined configs for IP Network Cloud & Host Nodes | ||
|
|
||
| ``` bash | ||
| make preplab | ||
| ``` | ||
|
|
||
| ## STEP #6 - Build Site Configs | ||
|
|
||
| Once you have adjusted your data model per site, you can build the configs with the following commands. We discuss the data models in the workshop. You can review the data model in the [Workshop Guide](https://aristanetworks.github.io/avd-workshops/avd/). | ||
|
|
||
| ``` bash | ||
| # Build Site 1 Configs | ||
| make build-site-1 | ||
|
|
||
| # Build Site 2 Configs | ||
| make build-site-2 | ||
| ``` | ||
|
|
||
| ## STEP #7 - Deploy Site Configs | ||
|
|
||
| The following will push your configurations to the switches per site. | ||
|
|
||
| ``` bash | ||
| # Build Site 1 Configs | ||
| make deploy-site-1 | ||
|
|
||
| # Build Site 2 Configs | ||
| make deploy-site-2 | ||
| ``` | ||
|
|
||
| ## STEP #8 - Test Traffic | ||
|
|
||
| Log on to a spine to verify OSPF neighbors and ip routes. | ||
|
|
||
| From `s1-spine1` | ||
|
|
||
| ``` bash | ||
| show ip ospf neighbors | ||
| show ip route | ||
| ping 10.30.30.1 | ||
| ``` | ||
|
|
||
| Log on to a host and ping to a remote host. | ||
|  | ||
|
|
||
| From `s1-host1` ping `s2-host2`. | ||
| ## **Lab Instructions** | ||
|
|
||
| ``` bash | ||
| ping 10.40.40.100 | ||
| ``` | ||
| The instructions to build and deploy this L2LS Multi-site topology are located in the Lab Guide **[here](https://aristanetworks.github.io/avd-workshops/avd-lab-guide/)**. |
