You're right, and I actually used the wrong term. What I need is the
default gateway, and there can be only one of that.
I'd add a status_t GetDefaultGateway(BNetworkInterfaceAddress&) to the
class to obtain that.
No, each default route can have its own gateway. The better metric decides where the packet goes to, and if two routes have the same metric, they should be alternated (not sure if we actually do the latter). 

Bye,
