For which type of endpoint entry does a Cisco ACI leaf switch keep the original TEP source address instead of rewriting the outer source IP address to its TEP address?

The correct answer is C. bounce entry. The difference between a bounce entry and a remote endpoint is in whether or not the leaf rewrites the outer source IP address of the packet. When a packet uses a normal remote endpoint, the Cisco ACI leaf uses its own TEP address as the outer source IP address, so the remote…

Explanation

The difference between a bounce entry and a remote endpoint is in whether or not the leaf rewrites the outer source IP address of the packet. When a packet uses a normal remote endpoint, the Cisco ACI leaf uses its own TEP address as the outer source IP address, so the remote leaf learns this packet with its own TEP. When a packet uses a bounce entry, the Cisco ACI leaf doesn’t rewrite the outer source IP address, so the remote data-plane learning will behave as if the packet came from the originating leaf rather than the intermediate "bounce" leaf. infrastructure/white-paper-c11-739989.html
