INE Vol 1 - Lab 21 - Controlling MPLS Label Distribution

This lab asks you to limit the traffic that should be label switched. It states that only traffic between R3 and R6's (the PEs) Loopbacks should be label switched. In order to do so, on the PE and P nodes, use 'mpls ldp advertise-labels for #' and an ACL to limit what prefixes are allowed to be labeled and what prefixes are not.

R1 - P node
R1#sh run | i 99
mpls ldp advertise-labels for 99
access-list 99 permit
access-list 99 permit
access-list 99 deny any log
