Description (partial)

Symptoms: DHCP unicast BootP offers can not be propagated back in the incoming
interface as the ARP entry is missing. This happens only when the relay
function is combined in a VRF and the incoming interface is unnumbered.

Conditions: The symptom is observed when SRD/SRE Cisco 7600 series router is a
DHCP relay/snooping agent. The request must come in a VRF.
