[j-nsp] dhcp-relay on MX

[Masood Ahmad Shah]

What you get when you do ---- show helper statistics
You can also use some packet capturing applications like ethereal on DHCP
server; just to check the packets are being forward to DHCP server or not.

If you need include the maximum-hop-count statement, deault value is 4 hops.
set the routing instance of the server to forward if different, include the
routing-instance statement.

Regards,
Masood

Still no luck. This is what I have. Also there is no firewall in this
network.
forwarding-options {
    helpers {
        bootp {
            server 10.0.0.100;
            relay-agent-option;
        }
    }
}

interfaces {       <-------client side
    ge-0/0/0 {
        unit 0 {
            family inet {
                unnumbered-address lo0.0 preferred-source-address 1.1.1.1;
            }
        }
    }
