Hi, this is my Linux Box
----------------------------
LAN 1 -----|--eth1 <---br1--->eth0.1 |
| \ |
| eth0--|----- 802.1q tagged 1 Mbps link
| / |
LAN 2 -----|--eth2 <---br2--->eth0.2 |
----------------------------
I have to bridge the 2 lans in the left side of the diagram with my linux box
running as a bridge. I have to tag the traffic of each lan so I created the 2
vlans interfaces on eth0 (tag 1 and tag 2).
All works fine. But now I have to priorize LAN1 traffic so it leaves the bridge
before LAN2. Also I need to shape the traffic to the 1 Mbps link.
I read about the "prio" qdisc but it honours the TOS field of the IP packets,
and I don't want to unless it was really necessary.
I read about the "prio" option of the htb qdisc and made some scripts, but they
don't work as I expected.
HTB script:
tc qdisc add dev eth0 root handle 1: htb
tc class add dev eth0 parent 1: classid 1:1 htb rate 1000kbit
tc class add dev eth0 parent 1:1 classid 1:11 htb rate 500kbit ceil 1000kbit prio 1
tc filter add dev eth0 parent 1: prio 1 protocol ip handle 1 fw classid 1:11
iptables -t mangle -A PREROUTING -i eth1 -j MARK --set-mark 1
tc class add dev eth0 parent 1:1 classid 1:12 htb rate 500kbit ceil 800kbit prio 2
tc filter add dev eth0 parent 1: prio 1 protocol ip handle 2 fw classid 1:12
iptables -t mangle -A PREROUTING -i eth2 -j MARK --set-mark 2
What do you suggest me?
Thanks in advance.
