10 | If you say Y here, then your Linux box will be able to act as an |
11 | Ethernet bridge, which means that the different Ethernet segments it |
12 | is connected to will appear as one Ethernet to the participants. |
13 | Several such bridges can work together to create even larger |
14 | networks of Ethernets using the IEEE 802.1 spanning tree algorithm. |
15 | As this is a standard, Linux bridges will cooperate properly with |
16 | other third party bridge products. |
17 | |
18 | In order to use the Ethernet bridge, you'll need the bridge |
19 | configuration tools; see <file:Documentation/networking/bridge.txt> |
20 | for location. Please read the Bridge mini-HOWTO for more |
21 | information. |
22 | |
23 | If you enable iptables support along with the bridge support then you |
24 | turn your bridge into a bridging IP firewall. |
25 | iptables will then see the IP packets being bridged, so you need to |
26 | take this into account when setting up your firewall rules. |
27 | Enabling arptables support when bridging will let arptables see |
28 | bridged ARP traffic in the arptables FORWARD chain. |
29 | |
30 | To compile this code as a module, choose M here: the module |
31 | will be called bridge. |
32 | |
33 | If unsure, say N. |
34 | |
35 | config BRIDGE_IGMP_SNOOPING |
36 | bool "IGMP snooping" |
37 | depends on BRIDGE |
38 | depends on INET |
39 | default y |
40 | ---help--- |
41 | If you say Y here, then the Ethernet bridge will be able selectively |
42 | forward multicast traffic based on IGMP traffic received from each |
43 | port. |
44 | |
45 | Say N to exclude this support and reduce the binary size. |
46 | |
47 | If unsure, say Y. |
