Reassigning IP Addresses

Adding New Nodes to a Full Subnet

Configuring a Secondary IP Address

Place Book Title Here
Suppose you must change network number 89 to 130.57. If the system does
not have multiple logical interfaces, you must change all IP addresses on
network 89 at the same time or lose connectivity to any host that did not have
its address changed.
With multiple logical interfaces, you can assign the new IP addresses
gradually. Networks 89 and 130.57 can coexist on the same network segment
until the transition is complete. The router interfaces, attached to both logical
networks, forward packets for each network and route packets between the
two.
Suppose you want to add several new nodes to a subnet that has no more
available IP addresses. Assume that the network has enough free connectors
available to physically attach the nodes.
First, you assign a new subnet number to the cable so that both subnets share
the cable. Then to add new nodes, you bind their IP address to the new logical
subnet. The router whose interface is bound to both subnet addresses provides
connectivity between the two subnets and to the rest of the internetwork.
A secondary IP address can be configured on the same interface that has the
primary IP address.
When multiple interfaces exist, the secondary address is associated with the
interface that is bound to an address that is on the same network. If there are
more than one interface on the same network, then you can select the interface
to add the secondary IP address. If the secondary address is not valid on any
of the networks bound to existing interfaces, the address is rejected and an
error message is produced.
To configure a secondary IP addresses, do the following:
