Dear All,
I am trying to find a way to filter intra-area OSPF filtering in a hub and spoke topology.
The objective is to prevent spoke to spoke routing advertisement.
Ospf import/export policies are designed to filter type 5 LSAs - cannot be used in our case.
Ospf network-summary-export policies are designed to filter type 3 LSAs - cannot be used in our case.
Another Alternative way is to utilize the martian address table of the spoke devices.
Do you have any other suggestions?
