Name is Brian glad to join up.
I just recently took and passed my ICND1 (in last month)
I also just took the ICND2 on 8/27/2016. I did not pass the exam I made a 815 but needed an 825. I am rescheduled to take this coming Thursday 9/1/2016. I actually feel pretty confident in my understanding of most of the material though I took a bit to long on the test and had to guest some questions on a frame relay lab in order to finish the test with like a minute left.
Its not so much the material that slows me down at the way they frame questions. Sometimes it feels like need a degree in understanding what they are trying to ask me (about 20-30% of questions but enough to slow me down and throw me off).
I am a new network admin working mostly with Brocade/cisco but no mentors or people around me as I moved from the server side of IT into the networking as the network engineer left.
hoping to be able to get some questions answered here and be able to ask at least educational networking questions as I dont have much in the way of mentors or people to talk to about networking.
one question area I found that I was not 100% up on was OSPF DR/BDR election.
I knew most everything from the books about exstart state and router ID but when a question was put out to me where it had point-to-point links mixed in with regular Ethernet and it asked about which routers would be the DR and which the BDR I was a bit confused. I knew that DR and BDR was not used in point-to-point protocols and it was only used in broadcast and nbma type environments as well as using multicast 220.127.116.11 but I found I was not positive if I needed to eliminated DR/BDR if they was a router that had a P2P connection.
I made a guess and eliminated those routers saying they could not be DR/BDR even though they had a higher Router-ID.
I know each broadcast domain has its own DR/BDR so I was thinking I may have made a mistake because I started wondering if the router connected to a P2P had an interface in another broadcast domain.
however, the only information given was the router ID and the connection type such as ethernet or P2P. (so basically a bunch of circles showing a line representing ethernet or a line representing serial and the router ID. I knew they were trying to be tricky so I just didn’t pick the highest router-ID as I thought they were trying to throw me off with the P2P)
Anyway I found this link on your site and hopefully it will answer my question if not I may come back because I want to have the small details to understand that question. in the past I probably have read enough that it might be expected to put everything together for that question but I never made that leap of understanding I guess.
