  1. Hi,

    In your explanation about LSA type 5, you wrote :
    “Here you can see the type 5 external LSA in the LSDB. Keep in mind that router R2 and R3 both are in area 0.”

    But, in the design, we can see that there are in area 1 ?


  2. Hi Rene ,

    That was great explanation. Thanks a lot for this.

    In the example of LSA1 , LSA2 , LSA3 types generation, I have setup the same lab in GNS3 but i cant see the DR abd BDR election.
    and Hence below type 2 LSA’s are not visible in the in my ospf LSDB which is appearing in your database.

    Net Link States (Area 0)

    Link ID ADV Router Age Seq# Checksum 31 0x80000001 0x008F1F


    COuld you please let me know if i am missing something here.


  3. Hello Brian

    Redistribution of E1 and E2 types is actually found within the realm of CCNP Route. Take a look at this Cisco link to see more.

    I hope this has been helpful!


  4. Hi Rene,

    I would like to know if I’ll be able to see in the show ip ospf database the type 4 LSA? I can’t seem to see it? All I can see is the router link, network link, summary link for inter-area and type 5 for redistributed routes into OSPF…
