no type 4 LSAs in the database

aueddonline

I have a lab set up running ospf and rip

I have a backbone area 0 and a stub area 10

one of the bacbone routers is also connected to a rip network and is redistributing the route into the OSPF domain.

this is all working fine type 5 LSAs are in the database ant in the route table as E2

I was expecting there to be some type 4 LSAs but there are non? how come?

Are the routes from the ASBR that are redistributed from the RIP network being sent to the ABR? I believe if they are being received by the ABR on area 0 then being sent out to area 10, you should see the LSA type 4 coming from the ABR port on area 10.

aueddonline

yes the external routes are seen by the ABR here are three of the topology table - internal router R1 - ABR R4 and R1 the ASBR
