[j-nsp] EX3200 DHCP forwarding

[Majdi S. Abbas]

	Given a fairly standard configuration:

	EX3200# show forwarding-options helpers bootp
	server A.B.C.D;
	interface {
	    vlan.XXXX;
	}

	(The vlan configuration consists of an IP address only.)

		And running 10.1R1.8 on an EX3200, why is this counter
	incrementing:

	EX3200> show helper statistics
	BOOTP:
	  Received packets: 25
	  Forwarded packets: 15
	  Dropped packets: 10
	    Due to no interface in DHCP Relay database: 0
	    Due to no matching routing instance: 0
	    Due to an error during packet read: 0
	    Due to an error during packet send: 0
	    Due to invalid server address: 0
	    Due to no valid local address: 10
	    Due to no route to server/client: 0

	The same apparent configuration works on another device.
What is meant by "no valid local address" -- the documentation is not
particularly enlightening on this point.

	Thanks,
