bridging two virtual devices?

["Tekale Sharad-FHJN78" <FHJN78@xxxxxxxxxxxx>]

Hi,

 

Is it possible to bridge two virtual devices?

 

$ vconfig  add eth0 1

$ vconfig  add eth0 2

$ifconfig

eth0      Link encap:Ethernet  HWaddr 00:00:00:00:00:00

          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:1342 errors:0 dropped:0 overruns:0 frame:0
          TX packets:445 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:170564 (166.5 KiB)  TX bytes:38443 (37.5 KiB)
          Interrupt:255 Base address:0x1000

 

eth0.0    Link encap:Ethernet  HWaddr 00:00:00:00:00:00

          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:1 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:0 (0.0 B)  TX bytes:319 (319.0 B)

 

eth0.1    Link encap:Ethernet  HWaddr 00:00:00:00:00:00
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

 

$ brctl addbr br0
$ brctl addif  br0 eth0.1
$ brctl addif  br0 eth0.2
$ brctl show
bridge name     bridge id               STP enabled     interfaces
br0             8000.000000d8d8fd       no              eth0.1
                                                                      eth0.2

 

Will there be any draw back due to such usage?

 

Or is such usage vaild?

 

Thanks and Regards,

Sharad.
