BGP question

Hi all,


I'm having difficulties to understand why I am not advertising a certain
customer range to my upstream.

I can see this range in my BGP table 3 times.


show ip bgp customer_range 

Number of BGP Routes matching display condition : 3

Status codes: s suppressed, d damped, h history, * valid, > best, i internal

Origin codes: i - IGP, e - EGP, ? - incomplete

    Network                    Next Hop                       Metric
LocPrf   Weight Path

*>i customer_range        Local IX                                     110
0          XXXX YYYY i

*   customer_range         upstream provider                       100
0          AAAA BBBB  XXXX YYYY i

*   customer_range         my customer                 0          120
0          YYYY YYYY i

       Last update to IP routing table: 0h23m34s, 1 path(s) installed:

       Route is not advertised to any peers


customer_range = each time the same /24


But it seems to choose the set the one as local IX as best.

When I disable local IX it sets the one with my upstream provider as best.


Shouldn't it set the customer_range I receive from my customer as best since
it's highest local pref and advertise it to my upstream provider peer?
