Hi,
We have a VPN setup with two Cisco 878 routers running advipservices and a 1.5Mbit/sec SHDSL link between both sites. Setup is briefly as follows
Site A:
int dialer0
ip addr 10.254.254.10
int vlan1
ip addr 192.168.1.0 255.255.255.0
site b:
int dialer0
ip addr 10.254.254.11
int vlan1
ip addr 192.168.2.0 255.255.255.0
We have a route from each router to forward the traffic to the other site for the respective subnet. The 10.254 addresses are assigned by our VPN provider as part of "ip address negotiated".
Our problem here is we wish to use QoS on this link however NBAR appears to only classify on input on the vlan1 interface - the dialer0 interface sees only traffic destined for the router's 192.168.x management IP. We're not running NAT or similar. This is showing clearly with the 'show ip nbar protocol-stat' command which shows what appears to be correct traffic on the vlan1 interface input but not on dialer1 in or out.
Can someone advise as to why this is happening and suggest a possible workaround.
IOS is 12.4(15)T1 advipservices.
Thanks.

I think you have to configure the match tunnel group for respective class map and priority for policy map. The following URL will guide you how to configure Quality of Service (QoS)

Hi,
Perhaps I should have called it a PN as opposed to a VPN - we're not using tunnels or ipsec, we're simply routing between both sites via a private network presumably configured using MPLS and other magic in 'the cloud'.
