Abstract

This disclosure describes various methods, systems, and devices related to identifying an issue in a network using a probe packet. An example method includes identifying an expired data packet transmitted in a network and addressed to a destination; generating a probe packet addressed to the destination; and forwarding the probe packet. When the probe packet is received, a report indicating a routing loop in the network can be transmitted to an administrator.
