[Anton.Schweitzer at o2.com]

Hi,
i have found some strange netflow cache entries which seems to be 
generated from an interface which has the
mpls netflow egress feature enabled :

1. 59.X and 62.X are not used and not routed in our network

2. Fa1/0.40 is the MPLS enabled Transit Lan between R1 und R2,
   and  Se4/0 the MPLS core interface which has mpls netflow egress 
enabled

3. I cant find any real packet (Sniffer, debug) with this IPs


Platform : 7513, IOS 12.3-9


Cheers
