Pavel, that is not what we are talking about, and you are wrong about distances. OSPF does not have AD of 0.
Mohamed, that is just basic rules what you are describing.
Here is the actual process of installing route to the routing table:
1. Routing protocol tries to install a new route into RIB.
2. RIB checks if that route is already present in the routing table. (route here being a combination of network and prefix, therefore 22.214.171.124/32 is a different route than 126.96.36.199/31 and are considered separately)
3. If it is not, it installs the route.
4. If it is already present, it asks the previous owner, to decide if the new route should be installed or not.
5. The old owner decides, if it will allow installation of new route or not, based on AD and or other internal mechanisms.
So you see, routing table itself is a passive mechanism and does not have a direct say in this. In our case, there is a static route, that tries to install itself in the routing table. RIB passes this route to the OSPF process and asks for the result.
OSPF does it's comparisons and for some reason prefers static over it's own route - this may be IOS OSPF implementation specific thing.
We have 3 identical switches configured by someone else and would like to claim some of the Gigabit ports(G1/G2/G3/G4) for use on servers. When we try to change the wiring and configuration, we run in to connectivity issues. Attached is a des...
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
