4.2(4.98a)

Description (partial)

Symptom:
DHCP response is dropped at the border leaf switch.

Conditions:
This issue could happen when all of the following conditions are met:

- DHCP is relayed between different VRF tables.
- The L3Out used for the DHCP relay has an underlying vPC connection.
- The hashing in the external router re-directs the DHCP server response to the other border leaf switch, which does not have the DHCP relay agent IP address.
