I have a Cisco 3725 router with IOS version "Cisco IOS Software, 3700 Software (C3725-ADVIPSERVICESK9-M), Version 12.4(12)". And this router is serving as a CE route for our MPLS connection to the service Provider. We do also have multiple VRFs ( around 10) and the WAN interface is DS3. So we created point-to-point subinterfaces and we put them in different vrfs. We have now transitioned to a new ISP and the ISP requested us to mark all of our outgoing traffics with DSCP AF31. So I have created the following policy-map
set ip dscp af31
class-map match-any TRAFFIC-OUT-WAN
Now we do have multiple GRE tunnel interfaces sourced from one of the WAN subinterface ( which is a member of VRF A). So the moment I applied the the policy-map on this WAN sub-interface (using the syntax "service-policy out TRAFFIC-OUT-WAN-AF31"), most of the GRE tunnels went down. And there is eBGP running on top of these GRE tunnels. Any idea please?
I did NOT checked that though! But I belive it might be a bug as the IOS is a bit old . The funny part is that some of the GRE tunnels are up and the BGP established on top of these GRE tunnels. But majority of the tunnels are down. I might have to open a ticket with CIsco...I will advice you my findings.

I am going to design and build an LAN network under a tunnel underground with long distance between the switches.
