Subject: [manet] DSR, source route question

Hello everybody,
another question about dsr source route. Let's assume the following graph:
I have read paragraphs 8.1.4, 8.1.5 and 3.3.2 before.

	S-----------A-----------B-----------------C
	|		|		|			|
	|		|		|			|
	F-----------G		+-----------------D-------------E
			|
			|
			H------------ X

The dotted lines between point means that those nodes are within wireless 
transmission range.
Initially S issue a route request for E, and the route replies sent back are 
S,A,B,D,E and S,A,B,C,D,E. G overhears them and put them in its route cache.

G's route cache:
-S,A ( from route request S->F)
-S,A,B,D,E (from route reply)
-S,A,B,C,D,E (from route reply)

H's route cache:
-S,A,G (from route request S->F)

Now H wants to send a packet to E, when G overhears that route request, G 
replies to H. How is H is going to get a packet to A in order to use that 
source route (S,A,B,C,D,E) ?
Sorry for the long post,

Jerry.
