Patent attributes
Embodiments of the present disclosure include techniques for detecting duplicate network device identifiers for routing protocols. A network device may receive a link state packet comprising a first network device identifier for use in a routing protocol. The network device may, upon determining that the link state packet satisfies a set of conditions, start a timer. The network device may, while the timer has not elapsed, maintain a count value of link state packets received that satisfy the set of conditions. The network device may, when the timer has elapsed, determine, based on the count value and a defined threshold value, that a second network device in the network is configured with a second network device identifier for use in the routing protocol that is the same as the first network device identifier.
