Question

Your team manages network fabric across two data centers, each fronted by a separate Cisco IOS XE RESTCONF endpoint. You must deploy the same set of VLAN resources to both devices from a single Terraform configuration, while keeping each device's credentials and host address distinct. Which Terraform approach correctly targets both devices in one apply?

Accepted Answer

Define two provider blocks with distinct alias values and reference them per resource using the provider meta-argument

Answer

Define a single provider block and switch the host attribute inside a lifecycle block for each resource

Answer

Run terraform apply twice with different -var files, since a configuration can only contain one provider instance

Answer

Use a single provider and pass the second device's host as a resource argument on each VLAN resource
