Abstract:
In [I-D.ietf-grow-route-leak-problem-definition], the authors have
provided a definition of the route leak problem, and also enumerated
several types of route leaks. In this document, we first examine
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 proposes an enhancement that significantly
extends the route-leak detection and mitigation capabilities of BGP.
The solution involves carrying a per-hop route-leak protection (RLP)
field in BGP updates. The RLP field is proposed be carried in an
optional transitive path 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. It is
not claimed that the solution detects all possible types of route
leaks but it detects several types, especially considering some
significant route-leak occurrences that have been observed in recent
years. 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.
