-Bridge configuration
-====================
-
-Before using slapformat  commands, you must set up a  bridge network interface
-named ``slapbr0''.  On that bridge,  you must set up  at least an  IPv6 global
-address, even if it is only a localhost one.
-
-On Debian systems, this is commonly done in ``/etc/network/interfaces'' file.
-
-Note that if  you declare any interface  as part of the bridge  (when you want
-your instances to be available not  only on localhost), you should remove them
-from the configuration file.
-
-Here is an example  of the bridge on eth0 device with  static IPv4 address and
-private IPv6 address:
-
-auto slapbr0
-iface slapbr0 inet static
-	address ADDRESS
-	netmask NETMASK
-	gateway GATEWAY
-	bridge_ports eth0
-
-iface slapbr0 inet6 static
-	address fd00::1
-	netmask 64
-
-You can have  a look at bridge-utils-interfaces(5)  and interfaces(5) manpages
-for further details.
