There is a limit how far an LSR can peek into the frame for loadsharing hash decisions (I recall 10 labels deep on the CRS). Other than that, the MTU is the limit. CRS can push a max of 7 labels onto the stack, ASR9k does 6.. Don't think there is any use-case (yet?) that would need to push that many labels. oli On 04/09/2012 15:45, "Pete Lumbis" <[email protected]<mailto:[email protected]>> wrote: If you are just talking about stack size, I think your only limit is MTU. If you are talking about the number of label that can be operated on, on a single device, that is going to be a limit of the platform/forwarding engine. -Pete On Tue, Sep 4, 2012 at 8:01 AM, Adam Vitkovsky <[email protected]<mailto:[email protected]>> wrote: Is there an upper limit on the number of labels in the label stack on Cisco boxes please?
