Abstract
In a system having multiple internal Internet protocol (IP) stacks, such as a network element, a value of a time-to-live (TTL) parameter may not be changed by an ingress IP stack. An indication of internal forwarding within the system may be used. An egress IP stack may decrement the value of the TTL parameter. A public network address for the system may be used for response packets to diagnostic packets received by the system.
