Subject: Re: Evaluation: draft-ietf-mpls-lsp-query - Multi Protocol Label Switching Label Distribution Protocol Query Message Description to Proposed Standard
This document describes the encoding and procedures for three
new Label Distribution Protocol (LDP) messages: Query Message,
Query-Reply Message and Partial Query-Reply Message. A Label
Edge Router (LER) sends a Query message when it needs information
about an established Label Switched Path (LSP). The Query message
can be used to request information about LDP LSPs as well as
Constraint-Based Label Switched Paths (CR-LSPs). The response to
the query is encoded into the Query-Reply and Partial Query-Reply
messages.
The Introduction should be rewritten so that is does not depend on the
Abstract to define terms.
In the security considerations, the document says:
The Query mechanism inherits the same security mechanism
described in Section 4.0 of [4].
Section 4.0 of RFC 3036 is the IANA Considerations! I assume that Section
5 should have been referenced. Further, section 5.1 of RFC 3036 discussed
the TCP MD5 Signature Option. This appear to be the only integrity
mechanism available. Since this protocol runs on top of TCP, why not
discuss IPsec ESP and/or TLS?
Section 5 of RFC 3036 also said that the peers need to be trusted to label
properly. What are the impacts on these new protocol messages if this
trust is misplaced? This topic should be discussed in the security
considerations section.
