Multi-Topology Routing

12.2(33)SRB 

MTR introduces the capability to configure service 
differentiation through class-based forwarding. MTR 
provides multiple logical topologies over a single physical 
network. Service differentiation can be achieved by 
forwarding different traffic types over different logical 
topologies that could take different paths to the same 
destination. MTR can be used, for example, to define 
separate topologies for voice, video, and data traffic classes.
