Instance ID
Enables multiple instances of OSPF to be run over a single link.
Each protocol instance would be assigned a separate Instance ID;
the Instance ID has local subnet significance only. Received
packets with an Instance ID not equal to one of the configured
OSPF Instance IDs on the receiving interface MUST be discarded.
So it sounds to me like you would have to set the instance ID on all routers in
the same subnet for each instance.
This would allow you to set different costs on an interface for the same subnet
on different instances.

I have two instances network-wide, one for private management and one
for public traffic.
That said, the cost seemed to propagate to the dynamic interface.

Just add the interface and make sure the network is in the correct
area. Instance ID has to do with running multiple instances on the
same interface which you most likely do not need to do.

So I'm trying to manipulate the OSPF costs on my network. I
create an interface (currently they're all dynamic) to specify
the cost. It asks for an Instance ID. Nowhere in my instance
specifications does it indicate what the instance IDs are. I am
running two instances, one public, one private.
Okay, let's just load up one of the dynamic entries and see what
it has...
BOTH PUBLIC AND PRIVATE INSTANCES SAY INSTANCE ID 0. How the hell
can that be? There are clearly two instances running by the fact
that on the interface screen, the interfaces have the various
corresponding instance names, but all on the same instance ID.
