WB3-LAB9-CONFIG.
----------------
Issue is between R2 and R4. R2 sees R4's Loopback (40.40.40.4) via R4
directly across the MLPPPoFR cloud.
However pings fail and traceroutes show a loop. its starnge that the
traceroute send the traffic to R5
where it loops back to R2 and so on.
Its strange. This in on PROCTORLABS vRACKS.
Due to this i failed to verify other tasks such as BGP btw R5 and R4. Its
not coming up of course.
I verified the MLPPPoFR setup as per the DSG. I also tried to erase/reapply
the configurations and also tried a power-cycle.
My rack session is over. I will try this Lab again on GNS3 later.
The resulkts of some show/traceroute are as follow.
ANY FEEDBACK GUYS.??!!
