3. How does it works?
Tunnel Interface + Linux Bridge+IEEE 802.1w (Rapid STP) Daemon =
Server-side Intelligent Switching
AzureVM# sudo rstpctl showport br0

5. Install rstpd and switch-setup
$ uname -a
Linux AzureVM 3.2.0-24-virtual #39-Ubuntu SMP Mon May 21 18:44:18 ..
$ sudo aptitude install bridge-utils module-assistant ; sudo module-assistant prepare
Download rstpd pacakge from http://git.kernel.org/?p=linux/kernel/git/shemminger/rstp.git
$ cd rstpd
$ sudo make ; sudo make install
$ sudo ip link add eoip0 type gretap remote X.X.X.X local Y.Y.Y.Y
$ sudo ip link add type veth
$ sudo ifconfig veth0 mtu 1462
$ sudo ifconfig veth1 mtu 1462
$ ifconfig veth0 up up
$ ifconfig veth0 up up
$ ifconfig eoip0 up up
$ sudo brctl addbr br0
$ sudo brctl addif br0 veth1
$ sudo brctl addif br0 eoip0
$ sudo rstpd
$ sudo rstpctl rstp br0 on
$ sudo rstpctl showport br0

6. Bridge/RSTP Aging Timer tuning
- Bridge STP Timer Config
$sudo brctl sethello br0 1
$sudo brctl setfd br0 4 Tunnel Tunnel Tunnel
$sudo brctl setmaxage br0 6
$sudo brctl setageing br0 10
Bridge + IEEE 802.1w
- Linux RSTP Timer Config
$sudo rstpctl sethello br0 1 (Rapid STP)
$sudo rstpctl setmaxage br0 6
$sudo rstpctl setfdelay br0 4
