MPLS and upstream and downstream

Post by Guest » Sat Jan 29, 2005 12:13 pm


http://www.cisco.com/warp/public/105/mp ... 6Referring to the question below from the link above : <quote>Q. Is R3 a "Downstream" LSR to R4 for 10.1.1.0/24?A. No, data flows from upstream to downstream.</quote>When I read the answer above, I felt there is a typo (any comment) , since the traffic flows from R4 through R3 to reach its final destination 10.1.1.0/24 , hence R3 downstream router to R4, because data flows from upstream  (R4) to downstream (R3) to reach its network destination (10.1.1.0/24). Any insight ?Regards

Please read this statement that precedes the question:"The R4 routing table has R1 and R2 as the "next-hops" to reach 10.1.1.0/24."As you see, R3 is therefore not consider a downstream router.Hope this helps,
