Hi Christian, hope you could share further information or correct me if I'm assuming something wrong regarding this PT. I'm trying to understand why at Step 5 point B (@ 12:00 in the vid) there's no change, whereas in my case after enabling the G0/0 interface on RC it became the DR. I was thinking it was due to it having been preconfigured with Priority 2, whereas RA and RB had Priority 1. Another similar DR modification happened at Step 7 point A (@17:15), in my case RB became DR after interface was re-enabled, but this time RB and RA both had the same priority, the only tiebreaker between them being the Lo0 interface IPs and it was even stranger as RC still had Priority 2 but became BDR!!! I shall be grateful for any comments regarding these issues, as this PT and its outputs really puzzled me. Thank you in advance!
Hello, thank you, first thing, the election of DR will not change until the current DR goes down, maybe you are expecting a change when you change the priority. The DR is elected for the highest router-id in OSPF, if router-id is not set, the highest loopback will be elected and if loopback is not set, the highest active ip in the router
@@romeroc24 Thank you for the conclusion. Though I'm still hesitant on how is it possible that a newly added router would become straight away the DR in a topology where there's already a DR and BDR and both of them are currently active? Again assuming some misconfiguraton or inconsistencies with the "debug/undebug all" commands, but just to be sure, shall redo the PT and revert with updates.
Hi Christian, after redoing the PT, this time the election process worked as intended. Thank you again for your prompt input!
@@damasta.md.99 Thank you for try again and to clear doubts
Very informative I am learning with you a lot. I am trying to do 10.11. 48 0/24 packet tracer vlsm desing and implementation practice.
Wonderful! and this is the video for vlsm th-cam.com/video/1AMC95P6a-E/w-d-xo.html
@@romeroc24 thank you Christian, but that is quiet different in what i trying to practice.
@@lissettevelec8718 use the same method and will work with different ip addresses and different number of subnets and hosts
@@romeroc24 thank you much! I am preparing for my exam in September. Happy to cross over your page. Any recommendations will be appreciated. Thank for taking your valuable time and reply me.
