When performing traceroute through a BIG-IP device, the traceroute utility may display the destination IP in place of the hop where BIG-IP is located, instead of a Self IP address of the BIG-IP device at that hop.
There is no impact to the performance of traffic through the BIG-IP device. The impact occurs only when reading and interpreting the results of a traceroute utility.
No return route for the client IP address exists on the BIG-IP device.
If possible and allowed, add route entry for the traceroute client subnet.
Traceroute through BIG-IP now displays a Self IP address of the BIG-IP device at that hop. This is correct behavior.
