Hi,
I have a GRE tunnel between an 3660 and a 3725. Under this tunnel there are many routers from SP, that we not even can see.
The problem is that at Netflow it shows me only a high GRE traffic, giving me only details if using Nbar but still like that loosing all of informations available at Netflow reports (Conversations, source, etc).
So, does anybody knows what should be configured at routers to enable netflow detailed informations of GRE tunnel?
Rds,

Can you supply a sample configuration.
I assume you have setup the following
Global
ip flow-cache timeout active 1
ip flow-cache timeout inactive 15
!
ip flow-export source FastEthernet0
ip flow-export version 5
ip flow-export destination net.flow.host.server 9996
!
Per interface
ip route-cache flow
Sorry to state the obvious

ip flow-cache timeout active 5
ip flow-export source Loopback0
ip flow-export version 5
ip flow-export destination [Server IP] 9996
interface Tunnel0
description tunnel vers rct2sin2
bandwidth 27000
ip address x.x.x.x x.x.x.x
ip mtu 1472
ip nbar protocol-discovery
ip route-cache flow
ip tcp adjust-mss 1432
load-interval 30
These are my confiurations and the router is a 3660.
Rds,
Alex
