NOTE: The S4248-ON switch supports only one default profile to reserve resources for overlay ARP entries.
To activate the profile after you configure an overlay routing profile, save the configuration and reload the switch.
Configure an overlay routing profile
● Enable an overlay routing profile in Configuration mode or disable the configured profile and return to the default.
OS10(config)# hardware overlay-routing-profile {disable-overlay-routing | balanced-
overlay-routing |
scaled-overlay-routing}
Display overlay routing profiles
● View the hardware resources available for overlay routing in different profiles; for example, in the S5200-ON series:
OS10# show hardware overlay-routing-profile mode all

DHCP relay on VTEPs
Dynamic Host Configuration Protocol (DHCP) clients on hosts in the overlay communicate with a DHCP server using a DHCP
relay on the VTEP switch. To work seamlessly, VTEP DHCP relay transmits the virtual-network IP address of the relay interface
to the DHCP server.
By default, DHCP uses the giaddr packet field to carry these addresses to the server. In a VxLAN, which has overlay and
underlay subnets in the same default VRF, DHCP relay on VTEPs operates without user intervention. However, in a VXLAN in
