Multi-Topology (MT) Routing in OSPF
P. Psenak, Sina Mirtorabi, Asim Kumar Roy, L. Nguyen, Padma Pillay-Esnault · 2007
This draft describes an extension to OSPF in order to define independent IP topologies called Multi-Topologies (MTs). The MT extension can be used for computing different paths for unicast traffic, multicast traffic, different classes of service based on flexible criteria, or an in-band network management topology. [M-ISIS] describes a similar mechanism for ISIS. An optional extension to exclude selected links from the default topology is also described.
