 Why don't you just use bridging with spanning tree?
 Will achieve exactly the thing you need.
 
 1. Create br0 on both machines
 2. Turn on spanning tree on br0
 3. Choose one of them to be root
 4. Assign tap0 and tap1 to br0 (tap0 having lower path cost)
 that's it.

Works like a charm :)

RE: [LARTC] Trying understand the HTB

[Flechsenhaar, Jon J]

The commands work but the structure doesn't seem right to me.  


Try this ...
tc qdisc del dev eth1 root
tc qdisc add dev eth1 root handle 1: htb default 40 
tc class add dev eth1 parent 1: classid 1:1 htb rate 10mbit 
tc class add dev eth1 parent 1:1 classid 1:40 htb rate 500kbit

Subject: [LARTC] Trying understand the HTB

Hi!

I am studying HTB. I used the topology showed below:

10.1.0.1 -- 10.1.14.25 (eth1) / 192.168.10.10 (eth0) -
192.168.10.11
(host 1)  (router)
  (host 2)

All machines use Debian Etch. Has a Iptables masquerading rule to eth1
in the router machine . The NICs are 100 Mb/s. The host 1 has Apache 2
and a file with 670 MB (CD ISO image) to download.

When I used wget to get http://10.1.0.1/file.iso from 192.168.10.11.
Without tc the speed showed by wget was 9.15 M/s (= 73.2 Mbits/s). The
iptraf confirmed it. Then I used these lines to control the traffic:

tc qdisc del dev eth1 root
tc qdisc add dev eth1 root handle 1: htb default 40 tc class add dev
eth1 root classid 1:0 htb rate 10mbit tc class add dev eth1 parent 1:0
classid 1:40 htb rate 500kbit

After tc rules, when I got file.iso, the speed showed by wget was 2.77
M/s (= 22.16 Mbits/s). But I used 500kbit (= 62.5 KB/s) in default
class.

My question is: why tc default class was configured with 500 Kb/s and
the real speed (confirmed by wget and Iptraf) was 22.16 Mb/s?

Thanks in advance.

Hi! Thanks for your response. I used your suggestion but the traffic
was 2.71 MB/s (21.680 Kb/s). I need 500 Kb/s. What is the error???

Thanks in advance.
