I think I either found a typo on this question, or need some clarification on it. The Question states:
-That AS 65500 is not advertising the prefix 192.168.12.0/22
-OSPF is being used as IGP
-Which addition will advertise the prefix?
- I answered "redistribute ospf 1" which now i think is a gotcha because the question never tells you which process ID OSPF is running on, but I answered that because you can redistribute OSPF routes into BGP.
BUT
-The answer listed as correct puts a static route to null0 at 192.168.12.0 but with a mask of 255.255.255.252 , which is a /30 and not a /22. If it was a /30 then BGP would not use this route to advertise to its neighbor because the specific prefic must be in the routing table, correct?
BTW, I'm taking my test tomorrow. I will post my results when I get them.
