# In this example we are going to assign topology tags using the tags.v2 workspace aware API
# More details on tag.v2 can be found at https://aristanetworks.github.io/cloudvision-apis/models/tag.v2/
# NOTE: Tag.v2 can be used for assigning both device and interface tags (studios, topology, etc) and it's not
# limited to topology tags only. 
# The following are some of the built-in tags that can be used to modify the Topology rendering:
# topology_hint_type: < core | edge | endpoint | management | leaf | spine  >
# topology_hint_rack: < rack name as string >
# topology_hint_pod: < pod name as string >
# topology_hint_datacenter: < datacenter name as string >
# topology_hint_building: < building name as string >
# topology_hint_floor: < floor name as string >
# topology_network_type: < datacenter | campus | cloud >
