Routing

Hi, 

I get this error whenever i try to change the SRGB range in Junos. 

[edit protocols isis source-packet-routing]
  'srgb'
    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 Seongsu,

It works! You're a guru 

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

0     16000   ISIS(A):1                  InUse  No

Thanks,
