This is part of the 802.1d spec probably to prevent possible loops. You can change address of bridge on recent kernels to be any of the addresses of the interfaces. As I remember, Debian Sarge kernel is ancient so you may need to run a newer kernel. > Best regards > Jason > > root at bridge:~> ifconfig > > br0 Link encap:Ethernet HWaddr 00:04:75:81:D2:1D > > inet addr:10.0.3.129 Bcast:195.30.198.255 Mask:255.255.255.128 > > UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 > > RX packets:826 errors:0 dropped:0 overruns:0 frame:0 > > TX packets:737 errors:0 dropped:0 overruns:0 carrier:0 > > collisions:0 txqueuelen:0 > > RX bytes:161180 (157.4 Kb) TX bytes:66708 (65.1 Kb) > > > > eth0 Link encap:Ethernet HWaddr 00:04:75:81:ED:B7 > > UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 > > RX packets:5729 errors:0 dropped:0 overruns:0 frame:0 > > TX packets:3115 errors:0 dropped:0 overruns:0 carrier:656 > > collisions:0 txqueuelen:100 > > RX bytes:1922290 (1.8 Mb) TX bytes:298837 (291.8 Kb) > > Interrupt:11 Base address:0xe400 > > > > eth1 Link encap:Ethernet HWaddr 00:04:75:81:D2:1D > > UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 > > RX packets:0 errors:0 dropped:0 overruns:1 frame:0 > > TX packets:243 errors:0 dropped:0 overruns:0 carrier:0 > > collisions:0 txqueuelen:100 > > RX bytes:342 (342.0 b) TX bytes:48379 (47.2 Kb) > > Interrupt:7 Base address:0xe800 > > > > lo Link encap:Local Loopback > > inet addr:127.0.0.1 Mask:255.0.0.0 > > UP LOOPBACK RUNNING MTU:16436 Metric:1 > > RX packets:1034 errors:0 dropped:0 overruns:0 frame:0 > > TX packets:1034 errors:0 dropped:0 overruns:0 carrier:0 > > collisions:0 txqueuelen:0 > > RX bytes:82068 (80.1 Kb) TX bytes:82068 (80.1 Kb) > >
