    Hi Ratnesh,
    My dtls connection is down between Cedge & vbond. My control connections are down, I attached the device to device template it attached to vmanage mode successfully , then I made some changes in transport vpn template routes and control connections went down with error TLOC disabled

      It seems like the changes you made in the transport VPN template affected the TLOC (Transport Locator) configuration, which caused the DTLS connection between your Cedge and vBond to go down.
      Here are a few steps you can check:
      TLOC Configuration: Ensure that the TLOC extension settings and routes in the transport VPN template are correct. This includes verifying the color and encapsulation (IPsec, GRE, etc.) settings. Incorrect TLOC settings could cause the connection to break.
      Transport VPN Routes: Review the changes you made to the transport VPN routes. If certain routes were deleted or incorrectly modified, this can affect the control connections, leading to TLOC disabled errors.
      vManage Sync: Sometimes when a device is moved to a vManage mode template, it may lose critical configurations needed for the control connections to function. Ensure the sync between vManage and the device is complete and successful.
      Interface & IP Connectivity: Check the interface settings and ensure IP connectivity between Cedge and vBond is still valid after the changes. The transport interface may have been impacted by the route changes.
      You might want to review the show control connections and show sdwan tlocs outputs to see which TLOCs are disabled and investigate further.

    The Authentication key for the Encryption with the IPSec VPN is wrong or Invalid.

    Only no shutdown or shutdown. The Debug events and packets command could have told to include something else.Okay! Public Key added for Peering! This is the configuration which is done before also. Okay! You might have changed the Root CA Certificate and updated the Public Key for Peering! Then The Local Certificate was connected with the Root Certificate and Certificate mismatch worked.

    Network is Not Reachable. Making Connection With The Other Route or You Are Using SRST Connection With Collaboration! Separate Connection For Troubleshooting!
