- ABSTRACT
-
- This document describes protocols that are part of the Multi-Level Path Vector
- (MLPV) routing scheme being developed for use in PIP internets. MLPV is a
- hierarchical routing scheme. It allows an arbitrary number of levels in the
- topological hierarchy and arbitrary interconnections within and across levels.
- Conceptually, the execution of MLPV in a PIP router consists of
- running multiple, independent instances of a path vector routing
- algorithm, one for each level of the hierarchy that routes are being
- computed. This document describes the MLPV topological model and
- specifies the basic path vector routing schemes used at various
- levels of the hierarchy.
