After IP unicast routing has been configured, you can configure the switch to forward DHCP or BOOTP requests coming from clients on subnets being serviced by the switch and going to hosts on different subnets. This feature can be used in various applications, including DHCP services between Windows NT servers and clients running Windows 95.
NoteIf DHCP/BOOTP Relay is enabled on a per VLAN basis, make sure it is enabled on both the client-side and server-side VLANs.
You can enable BOOTP Relay over VRFs and VPN-VRFs in the same manner as with normal VRs. For more information about BOOTP Relay over L3VPN, see L3VPN BOOTP Relay.
NoteBOOTP Relay show commands do not increment DHCP Release counters that are received from the client since DHCP release is hardware forwarded. Counters are incremented for other options in these commands.
