Lab-1 Task 6.4 Control Plane Protection (wk-II INE dynamips version)

error in workbook per this older post/thread:  http://ieoc.com/forums/p/11907/194706.aspx

".... 3. It is a small error in the verification part which ahs been fixed with the upcoming Vol2 updates. Basically you need to do a traceroute towards a destination that is IP switched not MPLS switched; all loopbacks,because of the MPLS task, will be MPLS switched and not match on your ACL :) try any other destination which is not MPLS switched like for example "traceroute 183.x.123.2 ttl 1 10" and you should see hints on your ACL and logs..... "



***Result using SolutionGuide verification***


traceroute 150.1.1.1 ttl 1 10   <-- issue is that this loopback is MPLS switched

Type escape sequence to abort.
Tracing the route to 150.1.1.1

  1 183.1.46.4 [MPLS: Label 35 Exp 0] 128 msec 140 msec 156 msec
  2 183.1.0.5 [MPLS: Label 35 Exp 0] 88 msec 92 msec 104 msec
  3 183.1.105.10 72 msec 60 msec 52 msec
  4 183.1.107.7 56 msec 72 msec 304 msec
  5 183.1.17.1 188 msec *  148 msec

 

***Correct Output***

traceroute 183.1.17.1 ttl 1 10    <-- use any non-MPLS switched IP address

Type escape sequence to abort.
Tracing the route to 183.1.17.1

  1 183.1.46.4 68 msec 64 msec 68 msec
  2 183.1.46.4 !A  *  !A
