Description (partial)

There's no immediate functional impact to customers as loopbacks are still being used to relay the DHCP traffic

The DHCP response does not reach the client.

This issue occurs when all of the following conditions are true:
- RsPathL3OutAtt is removed from an L3Out whose instp/EPG is used for DHCP relay.
- The DHCP server follows the behavior that it responds to the 1st DHCP requests and rejects the subsequent redundant ones.
- The relayed DHCP request with the removed RsPathL3OutAtt's IP is the first to reach the DHCP server.
