[nsp] BGP best route problem

[Nicolas DEFFAYET]

Hello,

I have a strange problem with a Cisco 2501 router.

The router don't flag sometimes the routes as best.

*>i2001:288::/32    3FFE:4013:4:2::1
                                            81    100      0 6175 109
17717 i
*>i2001:290::/32    3FFE:4013:4:2::1
                                                  100      0 1752 4725
3748 17832 17846 i
* i2001:298::/32    3FFE:4013:4:2::1
                                                  100      0 1752 4725
9600 i
* i2001:2A0::/35    3FFE:4013:4:2::1
                                           145    100      0 6175 4716 i

This problem is random, sometimes i have in routing table:
- no routes are best
- 2-3 routes are best only
- all routes are best (it's normal and good)

You can see a snapshot of a broken table (with 43 best routes only):

You can see in live the problem:
telnet route-server.ip.ndsoftware.net

Anyone have a idea about this problem ?

I have try many IOS version.

Thanks

Best Regards,
