  • 1.  Really stupid routing table rsvp question

    Posted 02-06-2016 13:15

    This is a stupid question but just to settle a disagreement:

     

    MPLS configured with RSVP and multiple LSPs between 2 PE routers

     

    If I run: show route x.x.x.x 

     

    The output includes:  #[RSVP/7/1] 1w1d 20:05:04

    A-to-B-01

    >A-to-B-02

     

    Does this mean that the currently selected LSP (in this example A-to-B-02) has been the active LSP for 1w1d 20:05:04 and that A-to-B-01 has not been in use for that particular route for that period of time?

    This depends on how load-balancing is configured, 

     

    try to add detail to show route  and see weight . If routes has same weight (usually 0x1 for active) this means that traffic is load balanced. 

    weight 0x8001 - bypass lsp

    Thanks (again)

     

    Tried that, both 0x1

     

    So does that mean although the carat is pointing at one LSP, both are actually in use?

     

    So if I am looking at a packet loss issue over MPLS and I find LSPs from ingress to egress are load-balanced, I have to trace out all LSPs involved in the load balancing?
