Note
Configuring Filtering in OSPF
The Filtering pane displays the ABR Type 3 LSA filters that have been configured for each OSPF
process.
ABR Type 3 LSA filters allow only specified prefixes to be sent from one area to another area and
restricts all other prefixes. This type of area filtering can be applied out of a specific OSPF area, into a
specific OSPF area, or into and out of the same OSPF areas at the same time.
OSPF ABR Type 3 LSA filtering improves your control of route distribution between OSPF areas.
Only Type 3 LSAs that originate from an ABR are filtered.
Note
To configure filtering in OSPF, perform the following steps:
In the main ASDM window, choose Configuration > Device Setup > Routing > OSPF > Filtering.
Step 1
Click Add or Edit.
Step 2
The Add/Edit Filtering Entry dialog box lets you add new filters to the Filter table or to modify an
existing filter. Some of the filter information cannot be changed when you edit an existing filter.
Choose the OSPF process that is associated with the filter entry from the OSPF Process drop-down list.
