we have a problem to filter ospf routes in our network. It doesn?t work with ACLs.
Then we followed the description of the document ?IOS Release 12.2T OSPF ABR Type 3 LSA Filtering?. Problematic is that the affected switch is a cisco catalyst 3750. This switch is not listed under the supported devices of the above-mentioned documentation. Nevertheless he ?knows? the commands. It doesn?t work (should it???).
What other possibilities are there for filtering ospf routes (concerning this type of switch)?
