Hi,
I want to setup a bridge without IP address, and I think the correct
way of doing so is to use the "manual" method of the inet family.
Something like this:
auto br2
iface br2 inet manual
bridge_ports none
bridge_stp off
bridge_fd 5
While such a bridge is nicely created and comes up, it doesn't get
deleted properly. Here's what happens:
host# ifup br2
Waiting for br2 to get ready (MAXWAIT is 12 seconds).
host# ifdown br2
bridge br2 is still up; can't delete it
run-parts: /etc/network/if-post-down.d/bridge exited with return code 1
This is because of a missing "ifconfig br2 down" call, which I solved
with the attached /etc/network/if-post-down.d/bridge file.
This file changes two things:
- it changes the order of things,
- it removes interfaces from the bridge,
- it adds an ifconfig down call on the bridge interface.
The reversal is IMHO needed since the up script does something in the
lines of:
create_bridge()
for all ports
add_port()
ifconfig port up
setup_bridge()
ifconfig bridge up
Hence, the logical destroyal (with respect to the pre-up script) should
be:
ifconfig bridge down
for all ports
ifconfig port down
remove_port()
del_bridge()
In your package it is:
del_bridge()
for all ports
ifconfig port down
