What happens if you have both interfaces active on the same network?
That is where the Duplicate Address Detection (DAD) kicks in. The DHCPv6 server will offer the same address on both interfaces, but the client will reject one when it sees it is already in use. In which case it depends on the server configuration if another address if offered or not.
I'm aware of DAD. But what happens when a DHCPv6 address is assigned to that DUID from 2 interfaces and one of them rejects it? I'm not running DHCPv6 on my LAN, so I can't check.
The client can use the address on the interface it configured with the assigned IPv6 address, wether or not the other interface receives an alternative address depends on the server configuration. Usually DHCPv6 is used for administrative reasons (keep track of who is doing what) and in that case it makes sense to not allow different addresses to be used. In which case it also makes sense to allow only one interface to be active at the same time (this reduces the burden of logging, since clients will always use the same IPv6 address, no matter how they connect). The lack of DHCPv6 support in Android limits the use to non-Android devices though, in which case it is not uncommon to block IPv6 entirely for that class of devices. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
