HP FlexNetwork MSR2003 User Manual

75
If DHCP server proxy is enabled, you must configure the sub-option 72 in Option 82 to carry the
index of the interface that processes the DHCP request. When receiving a DHCP response, the relay
agent forwards the response according to the interface index in sub-option 72.
To specify the source address and gateway address in DHCP requests:
Step Command Remarks
1. Enter system view.

N/A
2. Enter interface view.

N/A
3. Specify an IP address as the
source address and gateway
address in DHCP requests.

By default, the IP address of the
interface is used as the source
address and gateway address in
DHCP requests.

DHCP relay agent configuration example
Network requirements
As shown in Figure 32, configure the DHCP relay agent on Router A. The DHCP relay agent enables
DHCP clients to obtain IP addresses and other configuration parameters from the DHCP server on
another subnet.
Because the DHCP relay agent and server are on different subnets, you need to configure static or
dynamic routing to make them reachable to each other.
