  • 1.  RSVP admin-group question

    Posted 04-28-2022 05:36
    I have a route with two links to separate paths. IGP is ISIS.  RSVP is configured.  Before I applied admin-group to LSP, the LSP is up as follows:
    root@R11# run show mpls lsp name R11-R12 extensive
    Ingress LSP: 1 sessions
    
    192.168.1.12
      From: 192.168.1.11, State: Up, ActiveRoute: 0, LSPname: R11-R12
      ActivePath:  (primary)
      LSPtype: Static Configured, Penultimate hop popping
      LoadBalance: Random
      Encoding type: Packet, Switching type: Packet, GPID: IPv4
     *Primary                    State: Up
        Priorities: 7 0
        SmartOptimizeTimer: 180
        Computed ERO (S [L] denotes strict [loose] hops): (CSPF metric: 30)
     172.16.2.1 S 172.14.0.2 S 172.31.2.2 S
        Received RRO (ProtectionFlag 1=Available 2=InUse 4=B/W 8=Node 10=SoftPreempt 20=Node-ID):

    ​

    But after I applied admin-group, the LSP is down with From: 0.0.0.0

    set protocols mpls label-switched-path R11-R12 admin-group include-any blue
    
    root@R11# run show mpls lsp name R11-R12 extensive

    IGP is as follows:

    root@R11# run show route 192.168.1.12
    
    inet.0: 18 destinations, 18 routes (18 active, 0 holddown, 0 hidden)
    + = Active Route, - = Last Active, * = Both

                          to 172.16.1.1 via ge-0/0/0.0
                        > to 172.16.2.1 via ge-0/0/2.0
    


    Appreciate any insights and coaching !!
