Configuring Shared Networks with Cisco Network Registrar
Network Registrar supports multiple logical subnets on the same physical network segment. If you have several logical
subnets on the same physical network (for example, 192.168.1 and 192.168.46), you might want to configure DHCP
so that it offers addresses from both pools. By pooling addresses, you can combine two class C networks, or a Class B
and Class C network.
To join two logical subnets, first create two scopes, then select one to be the primary and the other to be the secondary.
Any client on the physical network will then obtain a lease from either scope on a round-robin basis (as long as the
client does not have a reservation or previous lease information).
1. Create a second scope that you want to make a secondary scope.
