Flow Label in the IPv6 header

[clavallee01]

Can anyone confirm that the Flow Label in the IPv6 header is used in VOIP and Video streaming over MPLS VPNS with Cisco and Juniper routers?

Thank you

Hi Craig,

I might be wrong, but as far as I know those 20 bits are still not being commonly used.

Ivan.

Ivan,

That is my opinion as well. I have not seen any common IPv6 application or driver to actually set the flow label in an IPv6 header to a non-zero value. Hence, even if Cisco or Juniper routers were somehow taking this field into account, it would not make much difference as it is currently being set to zero.

Best regards,

Peter

Agree Peter,

only a bunch of RFC'es prescribing its use exists :)
