L3 VPN on MPLS and QoS

Hi there


I've got some problems with QoS for one of our L3 VPN customers.


Our network consist of 76xx / SUP720-3B routers with SIP400 interfaces for core facing and various LAN interfaces for customer facing.


The customer VRF interfaces are configured as ordinary Vlan SVI's, e.g.


interface vlan123

ip vrf forwarding VPN

ip address 1.1.1.1 255.255.255.252

!


When setting up the VPN for QoS, I've done some digging and decided that "Short Pipe mode" is the right type for me. I've configred the system just as described in the manual for 7600 SR software, but I still don't get any QoS settings transferred across my network. Actually a "show mls qos" tell me, that I'm currently using "Pipe mode" for the MPLS VPN.


Anyone who might have some relevant information to share on QoS on L3 VPN MPLS.


Regards,

Lars

its been a while but Layer 2 cards are cheap cards and have no smart functionality. I thought pipe mode was for EoMPLS type functions and not layer 3 vpns.
