Subject: vswitch.xml: active-backup and balance-slb bonds must be one-sided.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d64e1870f4ad55e3f7eda8655b93c52d43442bfc;p=openvswitch

vswitch.xml: active-backup and balance-slb bonds must be one-sided.

It doesn't work to hook up an active-backup bond on one switch to an
active-backup bond on another switch, because they might pick different
active interfaces and therefore not pass any traffic.

The same is true of balance-slb because multicast and broadcast
traffic is dropped on ingress to any interface other than the active
interface.
