14.2 MPLS LDP

Tech Support,

I have a few issues with this lab that I'm hoping you can help me with.

#1 - The solution has you force the router's MPLS router-id to loopback 0.  Where in the requirement does it say to do this? 

#2 - The solution has you do "mpls ldp password required".  I know the problem requires authentication but where does it say that all MPLS ldp neighbor must use a password. As far as I can see you can still do authentication without this command.  Is this command an absolute requirement?

#3 - The solution does not have any routes to 54.1.1.0/24.  In my configuration that is a valid route off R6 Ser0/0/0 that is OSPF routing advertisements.

Would really like some feedback on these 3 items.

Thanks,

Andy
