Abstract:
The BGP4 protocol specifies the selection and propagation of a single
best path for each prefix. As defined and widely deployed today BGP
has no mechanisms to distribute alternate paths which are not
considered best path between its speakers. This behaviour results in
number of disadvantages for new applications and services.
The main objective of this document is to observe that by simply
adding new session between route reflector and it's client Nth best
path can be distributed. Document also compares existing solutions
and proposed ideas that enable distribution of more paths than just
the best path.
This proposal does not specify any changes to the BGP protocol
definition. It does not require software upgrade of provider edge
routers acting as route reflector clients.
