Re: [Xen-users] Can you put more than one physical nic on a bridge?

[Felix Kuperjans <felix@xxxxxxxxxxxxxxxxxx>]

I think both were probably connected to the same switch / hub in the
network. This causes a loop which often leads to strange failures.

You can put two interfaces on one bridge without problems, but one of
these criteria should apply:
- Only one interface is connected to a network at the same time, the
other one is unconnected
- The interfaces are connected to different networks
- The network supports fallback links with managed switches (this
usually only applies for servers) and is set up properly

As an alternative, you could consider routing with two interfaces, this
would never raise such problems, but is harder to achieve.

Regards,
Felix
