Symptom

During normal operation, the primary LISP router learns about the dynamic-EIDs and it gets synced with the secondary router. After the reload of secondary router, the learned dynamic entries will be flushed. The device comes up and the network convergence happens. But the dynamic EIDs never gets synced on the secondary router. This can lead to extended convergence times.

Conditions

Normal operation. Inconsistent EID's have been observed during normal operation sporadically and upon reload of the secondary router.

Workaround

Remove and re-add the map notify group command, for example: router lisp instance-id 1 dynamic-eid NAME no map-notify-group 239.1.1.1 map-notify-group 239.1.1.1 end
