One other filtering method that may be useful if questions forbid the mechanisms described so far is to use the area range command with the not-advertise option on an ABR and similarlry the same option on the summary-address command for an ASBR.

Which part? The distribute list can be done on any router since it only has
a local effect. The area filter-list, you're correct, must be done on an
ABR since it filters things going into or out of an area itself.

Scott,
just to clarify, this only applies to ABR I pressume...

The rule (per spec) is that all OSPF devices within an area must have an
identical database.
The distribute-list command works fine, but it's only inbound. And actually
it filters between the database and the routing table (see rule above).
You can do an area filter-list if you want, that filters a route from
entering (or leaving) an entire area. That's more specific than using a
stub type area, but still doesn't violate the above rule.
Cheers,
Scott

Who told you that you can't use a distribute list?

Hi
Are there any ways to filter ospf routes other than using "stub" network
type?
cant use distribute list or route maps to filter ospf routes ,So does it
mean that ospf isnt flexible as compared to eigrp or BGP ??
any comments?
