Release Information
Statement introduced before Junos OS Release 7.4.
Statement introduced in Junos OS Release 9.0 for EX Series switches.
Description
Enable TFTP or DNS request packet forwarding, or
configure the router, switch, or interface to act as a DHCP/BOOTP
relay agent. Use only one server address per interface or global configuration.
You can also use the helpers port statement to enable
forwarding LAN broadcast traffic on custom UDP ports to particular
servers as unicast traffic. Configure the UDP port number and optionally
an interface on which to listen for broadcast traffic, and the destination
server address to receive that traffic, as shown in either of the
following sample configurations:
user@ host# show forwarding-options
user@ host# show forwarding-options
helpers {
port 3000 {

fe-0/0/0.0 {

}
}
}
}
The remaining statements are explained separately. See CLI Explorer.
