Description Tommaso Pecorella 2014-03-14 18:36:20 UTC

When an interface has multiple IPv6 global addresses, the first one is always chosen, even if the two have different network parts.

I would like to thank Laura Heath for forcing me to test something that had to work: multiple global addresses on a node.
As a matter of fact, a node can have multiple IPv6 addresses. The problem was when the packets had to be transmitted.

Funny enough, with this bug a router with multiple addresses on a single device (the usual configuration for most low-end routers) couldn't work.

Not-so-funny enough, nobody noticed this.
