In fact, if a node attempts to use the interface ID in the noderef as a local zone index then the IPv6 connection will fail if the interface IDs do not match, as zone indices override the routing table if specified. For example:

Node A has an IP address of 2001:db8::1 on interface 1. Node A will publish 2001:db8::1%1 in its noderef. Node B's IPv6 default gateway is on its interface 2. If node B attempts to contact node A at 2001:db8::1%1 the request will fail. Node B must use 2001:db8::1 or 2001:db8::1%2 to contact node A, the former using the local routing table, the later specifying the local zone index.

Is there a reason the noderef includes the interface ID for each IPv6
address? I can't see how this would be relevant to a remote node.
