bridge0 on 7.2-release has no members

[kenbukan]

Hello,

the bridge0 is create but after /etc/rc.d/netif restart i havn't member on the bridge0.

If I comment out the line

ifconfig_bridge0="inet 172.16.106.50 netmask 255.255.255.0 up"

then I have member but no IP address on bridge0.

#######rc.conf

hostname="sheep3.xxxxx.net"
firewall_enable="YES"
cloned_interfaces="bridge0"
ifconfig_bridge0="addm em2 addm em3 up"
ifconfig_em2="up"
ifconfig_em3="up"
ifconfig_bridge0="inet 172.16.106.50 netmask 255.255.255.0 up"
defaultrouteer="172.16.106.1"
#ifconfig_em0="DHCP"
keymap="german.iso"
sshd_enable="YES"
usbd_enable="YES"

I have 4 Networkcards

em0 and em1 are RJ45 Gbit intel
em2 and em3 are FDDI Gbit Intel PCI Cards

I have compiled the kernel with if_bridge

How I configure bridge0 with member and ip address?

 

[SirDice]

ifconfig_bridge0="addm em2 addm em3 up"

ifconfig_bridge0="inet 172.16.106.50 netmask 255.255.255.0 up"

These two overrule each other. You have to note that most things in /etc/rc.conf are actually variables not commands.

http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/network-bridging.html

Not sure how you would assign the ip address to the bridge in /etc/rc.conf. You could try merging the two lines into one:

ifconfig_bridge0="addm em2 addm em3 inet 172.16.106.50 netmask 255.255.255.0 up"

Try

ifconfig_bridge0="addm em2 addm em3 inet 172.16.106.50 netmask 255.255.255.0"

It seems like your second ifconfig commands cancels the first one. Combine them.

I tryed

ifconfig_bridge0="addm em2 addm em3 inet 172.16.106.50 netmask 255.255.255.0"

and

ifconfig_bridge0="addm em2 addm em3 inet 172.16.106.50 netmask 255.255.255.0 up"

and now I have member but no ip address.

I try it also manually with

ifconfig bridge0 addm em2 addm em3 up
ifconfig bridge0 inet 172.16.106.50 netmask 255.255.255.0 up

and it works fine.

Ah, damn! I remember. This one always gets me!

If you start the bridge in /etc/rc.conf you must state additions to that bridge using an alias, or the first ifconfig statement will be overwritten by the second one.

Try:

ifconfig_bridge0="addm em2 addm em3 up"
ifconfig_bridge0_alias0="inet 172.16.106.50 netmask 255.255.255.0 up"

So it works fine.

Very big thanks for help.

I've searched for this answer for hours. Wouldn't it be smart to include this solution in the handbook?

@DutchDaemon, your method is working, thanks.

Need to add changes to the Handbook.

As this is a rather old thread, keep in mind that FreeBSD 7 (all versions) is now end-of-life and isn't supported anymore.

This method works on FreeBSD 10.
