38 | <para>
|
---|
39 | In this section we are going to discuss how to set up a network
|
---|
40 | bridge using <command>systemd-networkd</command>. In the examples
|
---|
41 | below, <replaceable>eth0</replaceable> represents the external
|
---|
42 | interface that is being bridged, while <replaceable>br0</replaceable>
|
---|
43 | represents the bridge interface.
|
---|
44 | </para>
|
---|
45 |
|
---|
46 | <para>
|
---|
47 | To create a bridge interface, create the following configuration file
|
---|
48 | by running the following command as the
|
---|
49 | <systemitem class="username">root</systemitem> user:
|
---|

59 | To assign a network interface to a bridge, create the following

60 | configuration file by running the following command as the

61 | <systemitem class="username">root</systemitem> user:

|
---|
71 |
|
---|
72 | <para>
|
---|
73 | Repeat the process for any other interfaces that need to be bridged.
|
---|
74 | Note that it is important that nothing assigns any addresses to the
|
---|
75 | bridged interfaces. If you are using <xref linkend="NetworkManager"/>,
|
---|
76 | <!--or <xref linkend="wicd"/>i,--> make sure you configure them to ignore
|
---|
77 | the bridged interfaces, as well as the bridge interface itself.
|
---|
78 | </para>
|
---|
79 |
|
---|
80 | <para>
|
---|
81 | If you are on a network which uses DHCP for assigning ip addresses,
|
---|
82 | create the following configuration file by running the following
|
---|
83 | command as the <systemitem class="username">root</systemitem> user:
|
---|
84 | </para>
|
---|
85 |
|

86 | <screen role="root"><userinput>cat > /etc/systemd/network/60-br0.network << EOF

|
---|
95 | Alternatively, if using a static ip setup, create the following
|
---|
96 | configuration file by running the following command as the
|
---|
97 | <systemitem class="username">root</systemitem> user:
|

111 | To bring up the bridge interface, simply restart the
