Hi,

 

A bit simplified situation – two 7304 boxes both of them acting as PE routers, one (A) of them is aggregation point for about 1000 ethernet customers (separate dot1q subinterface for each of them), another (B) is our AS border router towards upstream. There is MPLS core between them, running OSPF/BGP as IGPs. There are several logical links between them (dot1q subinterfaces on routers, VLANs in L2 network), and each of those links physically goes over different route (separate switches and other L2 features). Task is to configure router A to send traffic from several subnets/subinterfaces via one link, and traffic from other hosts via another link. Same about routerB side, traffic to specific subnets – via one link, rest of traffic – via another link. Perhaps I can do it with policy routing, but thats the last thing I’d like to do. If that helps in some manner - I can mark traffic with whatever suitable QoS marking or using prefix/access lists and then do some actions based on that.

 

Maybe MPLS TE can offer some opportunities here? What about directing traffic to some tunnels based on QoS markings? I know that those questions might sound a bit silly, but I’m new to TE and have very small experience with that. Out-of-list replies highly welcomed J
