        can't config SRGB
    error: configuration check-out failed

    Addtionally, how to check who resevered labels from Label Switching Database (LSD)?

    HI, 


    You have to configure explicit "chassis mode" that enhanced-ip when you want set SRGB on MX router.

    Maybe your MX router already booted enhanced-ip mode so i guess it cosmetic bug.

    Hi,

    >>> Addtionally, how to check who resevered labels from Label Switching Database (LSD)?

    If you want to check which protocol allocated a specific label, you can just use "show route label X", e.g. below label is allocated by RSVP:

     

    lab@vmx2_re> show route label 299856

    mpls.0: 17 destinations, 17 routes (17 active, 0 holddown, 0 hidden)
    + = Active Route, - = Last Active, * = Both

    299856 *[RSVP/7/1] 5d 14:16:25, metric 1
    > to 12.23.23.2 via ge-0/0/1.0, label-switched-path to_vmx5_around_the_world

     

    If on the other hand you want to get an overall picture regarding the amount of labels each protocol is able to allocate and has allocated, the following command might be helpful:

     

    lab@vmx2_re> show mpls label usage
    Label space Total Available Applications
    LSI 69609 69609 (100.00%) BGP/LDP VPLS with no-tunnel-services, BGP L3VPN with vrf-table-label
    Block 199936 199936 (100.00%) BGP/LDP VPLS with tunnel-services, BGP L2VPN
    Dynamic 487936 487930 (100.00%) RSVP, LDP, PW, L3VPN, RSVP-P2MP, LDP-P2MP, MVPN, EVPN, BGP
    Static 48576 48576 (100.00%) Static LSP, Static PW

    Hi, 

    Thanks for your reply! Unfortunately you can't tell from which range of labels is assigned to a particular protocol.  

    Like what i see on IOS XR,

    RP/0/RP0/CPU0:R1#sh mpls label table detail 
    Tue Mar 26 03:40:43.462 GMT-3
    Table Label   Owner                           State  Rewrite
    ----- ------- ------------------------------- ------ -------
    0     0       LSD(A)                          InUse  Yes
    0     1       LSD(A)                          InUse  Yes
    0     2       LSD(A)                          InUse  Yes
    0     13      LSD(A)                          InUse  Yes
    0     15000   LSD(A)                          InUse  No
      (Lbl-blk SRLB, vers:0, (start_label=15000, size=1000, app_notify=0)
    0     16000   ISIS(A):1                  InUse  No

    Thanks,
