Hi guys,
(Sorry for the previous post :S )
I had posted a question regarding bridges on OpenFlow list and got a terrific
explanation from Reid, as shown below:
Hypervisor
+--------------------------------------------------------+
| |
+------ | -- iface <--------------------------------------+ | |
| eth0 | |
| | | |
{network} | | |
| | v | |
| |
+------ | -- iface <---+ X------------------------> {IP stack} |
| eth1 | |
| | ^ |
| | bridge br1 | |
| | +---+ | |
| v | | (internal) | |
| port --+ +-- port -- iface <------+ |
| eth1 | | br1 br1 |
| | | VM 1 |
| | | +-----+ |
| | +-- port -- iface -- | | |
| | | tap1 tap1 +-----+ |
| | | |
| | | VM 2 |
| | | +-----+ |
| | +-- port -- iface -- | | |
| | | tap2 tap2 +-----+ |
| +---+ |
| |
+---------------------------------------------------------+
Now I need to fit the gateway inteface (gw-*) into this picture, which is bound
to dnsmasq and gives out IP addresses to the new instances. Can someone help me
with it ?
Also I need to know why doesn't 'ifconfig' show neither br-int nor an IP
address for tap interfaces of the instances (although I can sees instances have
an associated IP using dashboard) ?
Thanks,
Salman
