Technical Summary
This draft provides framework and requirements for Layer 2 Virtual
Private Networks (L2VPN) Operation, Administration and Maintenance
(OAM). The OAM framework is intended to provide OAM layering across
L2VPN services, Pseudo Wires (PWs) and Packet Switched Network (PSN)
tunnels. The requirements are intended to identify OAM requirement
for L2VPN services (i.e. VPLS, VPWS, and IPLS). Furthermore, if
L2VPN services OAM requirements impose specific requirements on PW
OAM and/or PSN OAM, those specific PW and/or PSN OAM requirements
are also identified.
Working Group Summary
This document has been reviewed by carriers and experts in the L2VPN WG
and there are no outstanding issues.
Document Quality
This document was reviewed by Mark Townsley and the L2VPN Chairs. The
document Shepherd is Shane Amante.
Note to RFC Editor
In Section 11. Security Considerations
OLD
This document takes into account the security considerations and
imposes requirements on solutions to prevent OAM messages from
leaking outside an OAM domain and for OAM domains to be transparent
to OAM frames from higher OAM domains, as specified in Section 6.10
and 7.10.
NEW
This specification assumes that L2VPN components within the OAM domain are mutually trusted. Based on that
assumption, confidentiality issues are fully addressed by filtering to prevent OAM frames from leaking outside their
OAM domain. Similarly, authentication issues are addressed by preventing OAM frames generated outside from
entering the OAM domain. Requirements to prevent OAM messages from leaking outside an OAM domain and for
OAM domains to be transparent to OAM frames from higher OAM domains are specified in Section 6.10 and 7.10.
