Hi Team I have query in OSPF implementation , We have an internal setup with 3 routers ( ZEBRA - zebra-0.93b.tar.gz ). And 2 routers are trying to update the 3rd router with same route say ( 172.25.25.0/24 ) but one is going to update by Type -3 LSA and other one via Type - 5 , In this scenario , type - 3 is getting added and no issues. But if u have already a Type - 5 External route in ur router and if u add the same route with Type -3 then issue starts. Type - 5 is getting deleted and Type - 3 is added , this is happening but again type - 3 is deleted so now there is no route in the router either by type -3 or type -5 , IS it a normal behaviour or an issue Please let us know comments on this issue --Sathya

A type 3 (which should come from an ABR) vs. a type 5 (from an ASBR) shouldn't be distributing the same route. A type three would distribute a route in a different ospf AS whereas a type 5 would be from a different routing protocol all together and are usually redistributed into the network manually. Either your design is seriously flawed or your explanation of the network is not sufficient to troubleshoot this issue.
