[nsp] BGP best route problem

[Turpin Mark Contr AFCA/GCF]

Sorry about html, I'm on the road.
 
I took a look:
route-server.ip.ndsoftware.ne>sh bgp ipv6 2001:200::/32
BGP routing table entry for 2001:200::/32, version 29040
Paths: (1 available, no best path)
Flag: 0x820
  Not advertised to any peer
  1752 4725 2500, (received & used)
    3FFE:4013:4:2::1 from 3FFE:4013:4:2::1 (195.140.149.2)

Have you tried turning synchronization off? 
 
Let me know if that helps,

	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):
	http://www.ip.ndsoftware.net/stats/bgp-table-snapshot.txt
	
	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,
