Configuring MTR

MTR overview

Multi-Topology Routing (MTR) splits a base topology into multiple topologies, which might intersect
or overlap with one another. Route calculation is performed on a per-topology basis.
For example, IS-IS MTR splits an IS-IS routing domain into multiple independent IP topologies, such
as an IPv4 topology and an IPv6 topology. It enables IS-IS to perform separate route calculation in
the IPv4 and IPv6 topologies.

Work mechanism

As shown in
can forward voice traffic through topology A and video traffic through topology B.
Router B does not belong to topology A. In topology B, the links between Router A and Router D and
between Router B and Router C do not exist. Route calculation and traffic forwarding are performed
in each topology independently.
