[j-nsp] Mixed vcf question

Hi James !

You wrote :
"For example for the layer3 (max routes supported, etc) why not the one of the QFX5100 acting as routing engine (and spine)?"

It would not help you at all if the routing engine can hold for example 300k routes and then only 100k can be downloaded to the forwarding engine.
Which one ? the first 100k ? so this obviously will not work, therefore the LCD ( least common denominator ) 
It is the forwarding engine or PFE which is in a mixed VCF the limiting factor.

Hi William
For example for the layer3 (max routes supported, etc) why not the one of the QFX5100 acting as routing engine (and spine)?

Is there something stated on the juniper.net site?

Cheers
James
