Hi, I'm creating a bridge, and then add to it two tap interfaces. No physical interface is added to the bridge. These are the commands: brctl addbr test ip tuntap add mode tap tap0 ip tuntap add mode tap tap1 ifconfig test up ifconfig tap0 up ifconfig tap1 up brctl addif test tap0 brctl addif test tap1 The problem is that the bridge doesn't seem to work correctly. I sent through tap0 some broadcast frames (WOL frames), and they didn't reach tap1. I was sending packets with: etherwake -b -i tap0 00:00:00:00:00:00 The tshark command for tap0 showed the frames being sent with tap0, but another tshark for tap1 didn't show them. Then I added to tap0 the IP address 192.168.10.1/24, and did: arping 192.168.1.2 I saw ARP request broadcast frames on tap0, but they didn't reach tap1. This is the output of ifconfig for test, tap0, and tap1 interfaces: root@computer:~# ifconfig test test Link encap:Ethernet HWaddr 02:07:b1:eb:2c:2a inet6 addr: fe80::944b:d9ff:fe10:b240/64 Scope:Link UP BROADCAST RUNNING PROMISC MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:19 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 B) TX bytes:3377 (3.2 KiB) root@computer:~# ifconfig tap0 tap0 Link encap:Ethernet HWaddr 02:07:b1:eb:2c:2a inet addr:192.168.10.0 Bcast:192.168.10.255 Mask:255.255.255.0 inet6 addr: fe80::7:b1ff:feeb:2c2a/64 Scope:Link UP BROADCAST RUNNING PROMISC MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:278 overruns:0 carrier:0 collisions:0 txqueuelen:500 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) root@computer:~# ifconfig tap1 tap1 Link encap:Ethernet HWaddr b2:ee:2c:f9:d5:0d inet6 addr: fe80::b0ee:2cff:fef9:d50d/64 Scope:Link UP BROADCAST RUNNING PROMISC MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:19 overruns:0 carrier:0 collisions:0 txqueuelen:500 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) The output of the brctl: root@computer:~# brctl show bridge name bridge id STP enabled interfaces pan0 8000.000000000000 no test 8000.0207b1eb2c2a no tap0 tap1 root@computer:~# brctl showmacs test port no mac addr is local? ageing timer 1 02:07:b1:eb:2c:2a yes 0.00 2 b2:ee:2c:f9:d5:0d yes 0.00 The output of route: root@computer:/home/iszczesniak# route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.2.0 0.0.0.0 255.255.255.0 U 2 0 0 eth1 192.168.10.0 0.0.0.0 255.255.255.0 U 0 0 0 tap0 169.254.0.0 0.0.0.0 255.255.0.0 U 1000 0 0 eth1 0.0.0.0 192.168.2.1 0.0.0.0 UG 0 0 0 eth1 What am I doing wrong?
