[mpls-linux-general] question about label.

From: Farazad F. <Far...@sa...> - 2005-01-03 07:51:07

Hi all.
I have a question about label in mpls.
I know that label stack is 32-bit value and label is 20-bit value in label 
stack ,I want to know that i can decrease this value,for example to 16-
bit.
regards.

I'm not sure what you mean.  Do you want to known where in the kernel
code you change the encoding/decoding of the MPLS shim?

Where?  In the kernel code and tools or when creating a LSP?  When configuring
a LSP, you can use any value from 16 to 2^20-1 therfore you can use any
16 bit value in that range.

What do you want to use the other 4 bits for?  The only whay to modify
this is to hack the kernel code.
