Symptom: In this case we can observe initial arp entry is installed after the first OFFER arrives from the server. After 5 minutes it goes into "probe" state and OFFERs are still arriving on the ASR9K, but ARP entry doesn't get renewed by OFFER messages. Conditions: 1. We have DHCP relay configured with broadcast policy check flag 2. Client is sending DISCOVERs constantly, but cannot get an ip address for some reason.
