10 | ---help--- |
11 | If you say Y here, then your Linux box will be able to act as an |
12 | Ethernet bridge, which means that the different Ethernet segments it |
13 | is connected to will appear as one Ethernet to the participants. |
14 | Several such bridges can work together to create even larger |
15 | networks of Ethernets using the IEEE 802.1 spanning tree algorithm. |
16 | As this is a standard, Linux bridges will cooperate properly with |
17 | other third party bridge products. |
18 | |
19 | In order to use the Ethernet bridge, you'll need the bridge |
20 | configuration tools; see <file:Documentation/networking/bridge.txt> |
21 | for location. Please read the Bridge mini-HOWTO for more |
22 | information. |
23 | |
24 | If you enable iptables support along with the bridge support then you |
25 | turn your bridge into a bridging IP firewall. |
26 | iptables will then see the IP packets being bridged, so you need to |
27 | take this into account when setting up your firewall rules. |
28 | Enabling arptables support when bridging will let arptables see |
29 | bridged ARP traffic in the arptables FORWARD chain. |
30 | |
31 | To compile this code as a module, choose M here: the module |
32 | will be called bridge. |
33 | |
34 | If unsure, say N. |

36 | config BRIDGE_IGMP_SNOOPING |
37 | bool "IGMP/MLD snooping" |
38 | depends on BRIDGE |
39 | depends on INET |
40 | default y |
41 | ---help--- |
42 | If you say Y here, then the Ethernet bridge will be able selectively |
43 | forward multicast traffic based on IGMP/MLD traffic received from |
44 | each port. |
45 | |
46 | Say N to exclude this support and reduce the binary size. |
47 | |
48 | If unsure, say Y. |
