New LAB:  

In general Same only few notes:
# v; x5 P6 X; g
1)the table they provide for layer2 :

+ {+ U+ B1 e; I' g. Q6 Svlan      Switch       ports   

& P! e( e2 [/ Q7 G: H2) alot of interfaces was shuting down from both ends routers and switches so in each router once I log in I do sh ip int brie | ex unass and then enable any port with ip configured.
! e' v+ q8 F9 O8 h' ~+ u
3 a5 b0 r+ ^8 }* A: o3) trunk ports shut down also .. there is a diagram telling you which ports are the trunks.

1 M8 ?- c$ ]1 d8 l% |4) a lot of preconfigurations all over the topology just they trick me with MPLS pre config .. but its not pre config in Jacob so I add it there and in per config they didnt put mpls ldp router id lo0 force so I added it also.

5) there pre config its always missing something so I double check all pre config they add.
