Description

Steps to reproduce the issue:

  1. Load T0 Topology to the DUT using MSFT Test bed.
  2. T0 Topology is successfully Loaded and DUT is up with T0 Topology
  3. Switch from T0 Topology to T1 Topology byLoading T1 Topology in Test bed
  4. Load T1 Topology config using "config load minigraph" command from Test bed.
  5. The T1 Topology is loaded successfully and T0 Portchannel are removed.
  6. When we issue "show ip interface" command still T0 Portchannel informations are present

Describe the results you received:

Describe the results you expected:

When the config load mini-graph command is executed all the Information about the previous topology has to be removed and only current topology information must be loaded

Additional information you deem important (e.g. issue happens only occasionally):

**Output of `show version`:**

```
(paste your output here)
```

**Attach debug file `sudo generate_dump`:**

```
(paste your output here)

Loading

The correct steps to switch from T0 to T1:

sudo ./testbed-cli.sh remove-topo <t0_testbed_name>
sudo ./testbed-cli.sh add-topo <t1_testbed_name>
sudo ansible-playbook config_sonic_basedon_testbed.yml -l <dut_name> -e topo=t1 -e deploy=true -e testbed_name=<testbed_name>

on DUT, do sudo config save -y

Hi Wendani,

I am following the same steps you have mentioned

  1. Deleted the OLD Topo
  2. Add the New Topo
  3. Load the Minigraph for the New Topo
  4. Save the Config

I see the Old config are still present in the JSON.
Actually the config load_minigraph command is not completely erasing the Old topo config and re-installing the new Topo Config.
Rather its just appending the new configuration on the old Configuration. This is causing the new and old topo configuration exist together. if you need any more details please feel free to contact me.
