# Bridging (Linux)
|
||
|
|
|
||
|
|
## General Remarks
|
||
|
|
|
||
|
|
`edge`s can be part of network bridges. As such, n2n can connect otherwise un-connected LANs.
|
||
|
|
|
||
|
|
## How To Use with `brctl`
|
||
|
|
|
||
|
|
... requires `-r`
|
||
|
|
... general syntax
|
||
|
|
... one example connecting two remote sites' LANs, including commands
|
||
|
|
|
||
|
|
## How it works
|
||
|
|
|
||
|
|
... remembers peer info MAC
|
||
|
|
... ageing
|
||
|
|
... internal MAC replaced inside usually encrypted packet data (no disclosure then)
|
||
|
|
... initial learning
|
||
|
|
|
||
|
|
## Broadcasts
|
||
|
|
|
||
|
|
... note on broadcast domain
|
||
|
|
|
||
|
|
## Compile Time Option
|
||
|
|
|
||
|
|
The `-r`option at edge does not differentiate between the use cases _routing_ and _bridging_. In case the MAC-learning and MAC-replacing bridging code
|
||
|
|
interfers with some special routing scenario, removal of the `#define HAVE_BRIDGING_SUPPORT` from `/include/n2n.h` file disables it at compile time.
