Configuration Example
IP A
PPLICATION
UDP needs to be forwarded Broadcast messages of common protocols usually
adopt UDP. The destination port number of UDP is configured to set the
transparent transmission protocol. For example, transparent transmission of TFTP
broadcast messages (port number 69) and DNS protocol broadcast messages (port
number 53) can be configured. At most 20 transparent transmission forwarding
protocols can be configured.
Perform the following task in system view.
Table 381 Configure transparent transmission forwarding protocol
Operation

I. Configuration Requirement
DHCP client host is in the network segment 10.110.0.0, while DHCP server is in
the network segment 202.38.0.0. DHCP relay router needs to relay DHCP
messages, so that DHCP client hosts can obtain configuration information such as
IP address from DHCP server through application.
DHCP server should be assigned with an address pool in network segment
10.110.0.0, so that it can assign proper address information to the DHCP client
host on the network segment. Meanwhile, the route to 10.110.0.0 should be
available on DHCP server.
