Known Affected Releases

4.2(3l)

Description (partial)

Symptom:
With DHCP in which the node is not properly decommissioned, the DHCP process released the IP address and allocated the IP address to another TEP, which caused a duplicate TEP and caused an outage.

Conditions:
If the node is not reachable during decommission and another node is commissioned at the same time, it is possible that the IP address released from the decommissioned node can be assigned to the new node.
