  Release:	10.04

    Installed: 1.1.0-14ubuntu2.1
    Candidate: 1.1.0-14ubuntu2.1
    Version table:

  Overview:

  Bonding + bridge does not work when bonding mode is set to active-
  backup and arp monitoring is enabled. (bond_arp_ip_target and
  bond_arp_interval)

  Reproducible: 100%

  1. Install ifenslave
  $ sudo apt-get install ethtool

  2. Install bridge utils
  $ sudo apt-get install bridge-utils vlan

  3. Use the following /etc/network/interfaces sample.
  auto lo
  iface lo inet loopback

  auto bond0
  iface bond0 inet manual
      post-up ifconfig $IFACE up
      pre-down ifconfig $IFACE down
      bond-slaves none
      bond-mode active-backup
      bond_arp_ip_target 10.153.107.1
      bond_arp_interval 100

  auto eth0
  allow-bond0 eth0
  iface eth0 inet manual
      bond-master bond0

  auto eth1
  allow-bond0 eth1
  iface eth1 inet manual
      bond-master bond0

  auto bond0.100
  iface bond0.100 inet manual
      post-up ifconfig $IFACE up
      pre-down ifconfig $IFACE down
      vlan-raw-device bond0

  auto bond0.200
  iface bond0.200 inet manual
      post-up ifconfig $IFACE up
      pre-down ifconfig $IFACE down
      vlan-raw-device bond0

  auto br0
  iface br0 inet static
      address 10.153.107.110
      netmask 255.255.255.0
      gateway 10.153.107.1
      bridge_ports bond0
      bridge_stp off
      bridge_fd 0
      bridge_maxwait 0

  auto br0-100
  iface br0-100 inet manual
      post-up ifconfig $IFACE up
      pre-down ifconfig $IFACE down
      bridge_ports bond0.100
      bridge_stp off
      bridge_fd 0
      bridge_maxwait 0

  auto br0-200
  iface br0-200 inet manual
      post-up ifconfig $IFACE up
      pre-down ifconfig $IFACE down
      bridge_ports bond0.200
      bridge_stp off
      bridge_fd 0
      bridge_maxwait 0

  Reboot the server. You won't be able to ping the br0 interface
  anymore.

  Workaround:

  Disable bond_arp_ip_target and bond_arp_interval and use MII
  monitoring. As follow below:

  auto lo
  iface lo inet loopback

  auto bond0
  iface bond0 inet manual
      post-up ifconfig $IFACE up
      pre-down ifconfig $IFACE down
      bond-slaves none
      bond-mode active-backup
      bond_arp_ip_target 10.153.107.1
      bond_arp_interval 100

  auto eth0
  allow-bond0 eth0
  iface eth0 inet manual
      bond-master bond0

  auto eth1
  allow-bond0 eth1
  iface eth1 inet manual
      bond-master bond0

  auto bond0.100
  iface bond0.100 inet manual
      post-up ifconfig $IFACE up
      pre-down ifconfig $IFACE down
      vlan-raw-device bond0

  auto bond0.200
  iface bond0.200 inet manual
      post-up ifconfig $IFACE up
      pre-down ifconfig $IFACE down
      vlan-raw-device bond0

  auto br0
  iface br0 inet static
      address 10.153.107.110
      netmask 255.255.255.0
      gateway 10.153.107.1
      bridge_ports bond0
      bridge_stp off
      bridge_fd 0
      bridge_maxwait 0

  auto br0-100
  iface br0-100 inet manual
      post-up ifconfig $IFACE up
      pre-down ifconfig $IFACE down
      bridge_ports bond0.100
      bridge_stp off
      bridge_fd 0
      bridge_maxwait 0

  auto br0-200
  iface br0-200 inet manual
      post-up ifconfig $IFACE up
      pre-down ifconfig $IFACE down
      bridge_ports bond0.200
      bridge_stp off
      bridge_fd 0
      bridge_maxwait 0
