[j-nsp] QFX CRB

[Cristian Cardoso]

I running 19.1R2.8 version on Junos.
Today I was in contact with Juniper support about a route depletion
problem and it seems to be related to the IRQs problem.
When the IPv4 / IPv6 routes are exhausted in the LTM table, the IRQ
increment begins.
I did an analysis of the packages trafficked on the servers, but I
found nothing out of the ordinary.
