Abstract:
[I-D.ietf-grow-route-leak-problem-definition] provides a definition
of the route leak problem, and also enumerates several types of route
leaks. This document first examines which of those route-leak types
are detected and mitigated by the existing origin validation (OV)
[RFC 6811]. It is recognized that OV offers a limited detection and
mitigation capability against route leaks. This document specifies
enhancements that significantly extend the route-leak prevention,
detection, and mitigation capabilities of BGP. One solution
component involves carrying a per-hop route-leak protection (RLP)
field in BGP updates. The RLP field is proposed be carried in a new
optional transitive attribute, called BGP RLP attribute. The
solution is meant to be initially implemented as an enhancement of
BGP without requiring BGPsec [I-D.ietf-sidr-bgpsec-protocol].
However, when BGPsec is deployed in the future, the solution can be
incorporated in BGPsec, enabling cryptographic protection for the RLP
field. That would be one way of implementing the proposed solution
in a secure way. The document also includes a stopgap method for
detection and mitigation of route leaks for an intermediate phase
when OV is deployed but BGP protocol on the wire is unchanged.
