Step 6
Assigning IP Addresses to SVIs
To configure IP routing, you need to assign IP addresses to Layer 3 network interfaces. This enables
communication with the hosts of those interfaces that use IP. IP routing is disabled by default, and no IP
addresses are assigned to SVIs.
An IP address identifies a location to which IP packets can be sent. Some IP addresses are reserved for special
uses and cannot be used for host, subnet, or network addresses. RFC 1166,
“ Internet Numbers, ” contains the
official description of IP addresses.
An interface can have one primary IP address. A mask identifies the bits that denote the network number in
an IP address. When you use the mask to subnet a network, the mask is referred to as a subnet mask. To
receive an assigned network number, contact your Internet service provider.
Follow these steps to assign an IP address and a network mask to an SVI:
