"OPSF Hub-And-Spoke And Virtual Links" lab - Issue

Got stumped on a portion of this "OPSF Hub-And-Spoke And Virtual Links" lab (Bryant advantage). Hopefull I can finish it tomorrow... sleepy...


NOTE: My Physical Setup is the as the workbook's, except that the Lab's R3 is my R4,
and the lab's R4 is my R5. Hence the slight differences in loopbacks and the like.

I am working the "OPSF Hub-And-Spoke And Virtual Links" lab. What I
am running into is that I am unable to establish an Adjacency between
R4 and R5. Any suggestions would greatly appreciated. Thanks!
