[j-nsp] aggregate route color

[Douglas Marschke]

All color is defined as is preference 3 and 4.  So if you have 2
destinations the tie-breaker rules are:

Prefer route with best preference
Prefer route with best preference2
Prefer route with best color
Prefer route with best color2

Below is a static and aggregate route with the same preference (5) but a
different color (0 vs 3), thus the static route is active:

Hi,
 
I was reading JunOS docs, and don't understand how to use "color" option
to provide route preference for aggregate route.
Do anyone have an example?
Thanks.
