Answer is C as Bootstrap priority will always be preferred over  Auto-RP (tested on MX routers last night)

All answers are correct and I'm gonna use the exam answers.
In my opinion there should be only one correct answer which is B (routes from R1 - eBGP session). Both R3 and R4 should get the same treatment and since we have "no-client-reflect" configured we should not reflect the routes from R5. Following the same logic why would we advertise the route to R4 but not R3? Can someone chime in?

RR will reflect routes from R1 to R5 as it has ebgp session with R1 so B is correct
RR will also reflect routes from R2 to R5 as R2 is not part of cluster group hence doesn't fall under "no-client-reflect" configuration so C is also correct

Dear Batt,

Also please confirm the following as PE will receive the same label with traffic which it will advertise to PE according to following formula:

Tx Label= Remote Label Base + Local Site ID - Remote Label Offset= 2500+4-1= 2503

https://www.dropbox.com/s/rqziuvwlfmm19rk/VPLS%2049.png?dl=0

I think correct answer should be 3001 (D) because the question is referring to incoming label (not outgoing label which is 2503). incoming label is label base + remote side ID - label offset = 3000 + 2 -1 = 3001,
Do you agree?
