network bridging and start script (solved)

The existing configuration stub for bridging is not supported by the actual version of the network start script (/etc/rc.d/network). Here the modifications to include bridged networking into the network management:

# in /etc/conf.d/bridges: modified format for bridge member interfaces
bridge_br0=(eth0 eth1)

# in /etc/rc.d/network: included support for bridge interfaces (see #BRIDGE-marks)
#!/bin/bash

. /etc/rc.conf
. /etc/rc.d/functions

# BRIDGE
# look for bridge settings
[ -f /etc/conf.d/bridges ] && . /etc/conf.d/bridges

# look for wireless settings
[ -f /etc/conf.d/wireless ] && . /etc/conf.d/wireless

# look for ethernet bonding settings
[ -f /etc/conf.d/bonding ] && . /etc/conf.d/bonding

# look for dhcpcd settings
[ -f /etc/conf.d/dhcpcd ] && . /etc/conf.d/dhcpcd

# Special wrapper for hotplug ifup calls
#  (make sure hotplug doesn't bring up disabled interfaces)
hotplug_ifup()
{
        [ "$1" != "" ] || return 1
        for ifline in ${INTERFACES[@]}; do
                # if the interface is disabled then this will be skipped
                if [ "$ifline" = "$1" ]; then
                        ifup $ifline
                fi
        done
}

ifup()
{
        if [ "$1" = "" ]; then
                echo "usage: $0 ifup <interface_name>"
                return 1
        fi
# BRIDGE
        for brif in ${BRIDGE_INTERFACES[@]}; do
                if [ "$brif" = "${1}" ]; then

        done
        return $?
}

# from here unmodified /etc/rc.d/network

Hope this helps anybody.

Re: network bridging and start script (solved)

Nice one, Nazdravi. You should post a bug report on this - the devs don't always read the forum.
