L2VPN WG Meeting

IETF 65

Dallas, TX, USA

WG Document Status (1/4)I-D’s previously “On Hold”, pending resolution of Security

Area review: • Cleared DISCUSS:

– draft-ietf-l2vpn-vpls-ldp-08– draft-ietf-l2tpext-l2vpn-07

• draft-ietf-l2vpn-vpls-bgp-06– Needs paragraph included from RFC4364, §13.1, to clear

DISCUSS.– Paragraph unifies security between L3VPN & L2VPN.

• draft-ietf-l2vpn-signaling-07– Needs a paragraph to say that for manually instantiated tunnels

refer to RFC4023; for auto-discovered tunnels over IP, it is desirable to have a more automated method to secure the traffic – however, that is out-of-scope for this document and will be looked at in the future.

WG Document Status (2/4)

• draft-ietf-l2vpn-requirements-06– Does not adequately address §4.5.1, User Data

Security, of RFC 3809.• l2vpn-reqmt’s should address this in the same manner as

§6.9.1 (Support for Securing Customer Flows [over the Internet]) of RFC 4031 to make L3VPN & L2VPN consistent.

– Need to reconcile §6.10.4, Security Considerations for Multi-Provider L2VPN’s, from RFC4031 with l2vpn-reqmt’s.

• l2vpn-reqmt’s has multi-provider requirements, but less specific security language than RFC4031.
