I have a server with two network adapters. I configured bonding and it works. Here's the working configuration:
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet manual
bond-master bond0
bond-primary eth0
auto eth1
iface eth1 inet manual
bond-master bond0
auto bond0
iface bond0 inet static
bond-mode balance-rr
bond-miimon 100
bond-slaves none
address 192.168.1.2
gateway 192.168.1.1
netmask 255.255.255.0
dns-nameservers 192.168.1.13
I try to add a bridge, but then, the machine loses connectivity.
I tried:
To specify the same IP address, gateway, netmask and nameserver for both
bond0andbr0, or to specify ones forbr0only,To add
post-up/pre-downtobond0,To add
pre-up/post-downtobr0,Clone the solution by Benjamin Franz (adjusting the IP addresses accordingly),
Clone the solution by Kendall Gifford (adjusting the IP addresses accordingly).
For example, the following configuration doesn't work:
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet manual
bond-master bond0
auto eth1
iface eth1 inet manual
bond-master bond0
auto bond0
iface bond0 inet static
bond-mode balance-rr
bond-miimon 100
bond-slaves none
auto br0
iface br0 inet static
bridge_ports bond0
bridge_maxwait 0
bridge_fd 0
post-up ifup bond0
post-down ifdown bond0
address 192.168.1.2
gateway 192.168.1.1
netmask 255.255.255.0
dns-nameservers 192.168.1.13
What else can I try to make it work?
It somehow works by:
Removing any post-up/pre-down/pre-up/post-down,
Adding the IP address, gateway, netmask and nameserver for both
br0andbond0.During the boot, I consecutively see the following messages from
/etc/init/failsafe.conf:but once the boot is finished, the machine appears to be connected to the network.
The final configuration looks like:
Brings up interface only if there are ip configuration. To bring up interface without ip configuration you must use:
So fix your configuration to:
