| 42 | <para>
|
---|
| 43 | In this section we are are going to discuss how to set up a network
|
---|
| 44 | bridge using <command>systemd-networkd</command>. In the examples
|
---|
| 45 | below, <replaceable>eth0</replaceable> represents the external
|
---|
| 46 | interface that is being bridged, while <replaceable>br0</replaceable>
|
---|
| 47 | represents the bridge interface.
|
---|
| 48 | </para>
|

|

|
---|
| 51 | To create a bridge interface, create the following configuration file
|

| 52 | by running the following command as the

|
---|
| 76 | <para>
|
---|
| 77 | Repeat the process for any other interfaces that need to be bridged.
|
---|
| 78 | Note that it is important that nothing assigns any addresses to the
|
---|
| 79 | bridged interfaces. If you are using <xref linkend="NetworkManager"/>
|
---|
| 80 | or <xref linkend="wicd"/>, make sure you configure them to ignore
|
---|
| 81 | the bridged interfaces, as well as the bridge interface itself.
|
---|
| 82 | </para>
|
---|
| 83 |
|
---|
| 84 | <para>
|
---|
| 85 | If you are on a network which uses DHCP for assigning ip addresses,
|
---|
| 86 | create the following configuration file by running the following
|
---|
| 87 | command as the <systemitem class="username">root</systemitem> user:

| 99 | Alternatively, if using a static ip setup, create the following
|
---|
| 100 | configuration file by running the following command as the
