Hi ,
  I'm not able to get this why this virtual link not coming up , this is the 2nd day i'm putting on this and my exam is near....
   
  max-metric lsa is because there is a requirement that to transit R1 only if R2 is down ....

  Why do you have 'max-metric router-lsa' configured on R1?

Can you post the configs for all of R1 as well?

plus 'sh ip ospf nei' and 'sh ip ospf inter' for both R1 and R3

  Why is R3 building its virtual link to 150.1.3.3 ? Isn't this R3's own Router ID. Looking at your config below, I would expect R3 to have two virtual links, one to 150.1.1.1 and the other to 150.1.2.2 ?
