ASR901 error "pstorm_bcm_prog_label"

I have a trouble with ASR901,

I have many vrfs work normally, then appears many logs in my console and vrfs stop working.

Somebody knows how to fix this trouble?

ASR901 error "pstorm_bcm_prog_label"

Hello Juan,

I can see you are very close to label scale limit, for ASR901 platform there is a limit of 4000 hw switched labels. I would suggest you to decrease the amount of prefixes on this box. You can evalute any possible way to do so, summarization, filtering etc.

Thank you

ASR901 error "pstorm_bcm_prog_label"

Hello Juan,

Would you be so kind to provide "show version" output. It's most likely you are hitting a scale limit on the box due to a large amount of labels allocated for MPLS services.

You can check when the first messages appeared and correlate to amount of MPLS service deployed on the box prior that time.

Thank you

ASR901 error "pstorm_bcm_prog_label"

Hello Juan,

Would you be so kind to capture the following outputs:

! Configure "service internal"

(conf)# service internal

# show platform hardware cef hw-resource

We need to calculate the overall label allocation on the box in order to understand did we cross the scale limit on this router.

thks...

Actually, I applied your suggestions.. ... It works

ASR901 error "pstorm_bcm_prog_label"

Hi Dmitry,

the 4000 hw switched label limitation on the ASR901, is it applies only on MPLS L3VPN ?

or is it shared with EoMPLS ?

Thanks,

Budi L
