Description (partial)

In a Nexus 5500/5600/6000 switches in fabricpath environment, broadcast DHCP offers might not get relayed under certain conditions.

Fabricpath setup with DHCP relay configured on more than 1 switch. DHCP offer sent as broadcast follows multi-destination tree and hits another Relay agent in the setup. Instead of forwarding the offer down the multi-destination path DHCP offer is redirected to CPU and dropped.
