LARTC - Apr 2004 - [Fwd: HTB in 3 levels for shaping on both VLAN and QOS]

I have 4 VLANs which i would like to give different priority on our

internet connection. I would also like to shape traffic, according to 
its FWmark, in EACH VLAN. I have created this setup, with a HTB classes 
in a HTB class in a HTB class. (3 levels).

           ROOT IMQ1 QDISC 1:0
                   |
                  HTB 1:1                    (HTB AT LINE UPPER LIMIT)
                   |
   /----------------------------------\
   |          |           |           |
HTB 1:11   HTB 1:12    HTB 1:13    HTB 1:14  (HTB CLASS FOR EACH VLAN)
   |          |           |           |
_______    _______     _______     _______

I fist filter on source IP-Address:
tc filter add dev imq1 protocol ip parent 1:0 prio 1 u32 match ip src 
xxx.xxx.xxx.0/24  classid 1:11

I then filter on fwmark:
tc filter add dev imq1 parent 1:11 protocol ip prio 1 handle 20 fw 
classid 1:110

Can anyone tell me if this is a good or bad idea, or if there is a 
better way to do it?
