*** 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
