*** Test Cases ***
Sanity E2E Test for OLT/ONU on POD for DT
    [Documentation]    Validates E2E Ping Connectivity and object states for the given scenario:
    ...    Validate successful DHCP/E2E ping (no EAPOL and DHCP flows) for the tech profile that is used
    ...    Traffic sent with same vlan from different RGs,
    ...    should reach the NNI port on the OLT with the expected double tagged vlan ids
    ...    Inner vlans from the RG should not change

Test Subscriber Delete and Add for DT
    [Documentation]    Validates E2E Ping Connectivity and object states for the given scenario:
    ...    Assuming that all the ONUs are DHCP/pingable (i.e. assuming test1 was executed)
    ...    Delete a subscriber and validate that the pings do not succeed and state is purged
    ...    Disable and Enable the ONU (This is to replicate the existing DT behaviour)
    ...    Re-add the subscriber, and validate that the flows are present and pings are successful
