B-9

Parameter: Import Mask

Path: Configuration Manager > Protocols > IP > Route Filters > OSPF > Import

Filters

Default: 0.0.0.0

Options: Depends on the address class of the import address

Function: Specifies the range of addresses upon which this filter acts.

For example, consider Class B network 172.32.0.0. The address mask directs

the filtering process to a specific portion of the IP address. In other words, any

IP address that matches the masked portion of 172.32.0.0 is subject to filtering.

If 255.255.0.0 is entered at Import Mask, only the Net ID portion of the address

will be filtered. If the mask 255.255.255.0 is entered at Import Mask, the Net ID

and Subnet ID portions of the address will be filtered.

If the Import Address field is set to 0.0.0.0, and the Import Mask is set to

0.0.0.0, then the filter applies to all routes. If the Import Address field is set to

0.0.0.0, and the Import Mask is set to 255.255.255.255, then the filter applies to

the default route.

Instructions: Enter the appropriate mask in dotted-decimal notation.
