IPv4 DHCP asymmetric routing OS10 does not support DHCP relay with IPv4 asymmetric routing. OS10 supports DHCP relay with IPv6 asymmetric routing. The DHCP relay agent listens on the best DHCP server path. If the DHCP OFFER packet is sent through a path that the DHCP relay agent is not listening on, the DHCP OFFER packet drops. In this case, the DHCP client-enabled interface does not receive the IPv4 address. For example, in the following topology, the DHCP DISCOVER packet is sent by the relay agent (R4) on link 2. The relay agent routing table points only to link 2 to reach the DHCP server. However, the DHCP server sends the DHCP OFFER packet to relay agent (R4) on a different path and the DHCP OFFER packet drops. This issue occurs because the relay agent listens only on the best path uplink interfaces where the DHCP server is reachable. 146 System management
