[c-nsp] Link affinity

[Johan Borch]

Hi!

I'm trying to understand how to get administrative groups/link-coloring in
JunOS to play with link affinity in Cisco/IOS. But I don't understand it.

In JunOS you assign the bit position 0-31 to the MPLS interface and then
use the names on your LSP, thats easy.

What I don't get is how to mask this onto IOS.

lets say it have 3 groups:
Bit position 1
Bit position 2
Bit position 3

How to I use link affinity/mask to use 1 and 2 in IOS or a link
affinity/mask to use position 1 and 3? Do anyone have experience with this?

Best regards
Johan
