Multi-Topology Routing

Multi-Topology Routing (MTR) is a feature of Cisco IOS routers that allows them to define multiple topologies within a network. Each topology is essentially a subset of the routers and links in a network. MTR allows a separate set of routes to be calculated for each topology.

Protocols with MTR support:

• OSPF
• EIGRP
• IS-IS
• BGP
