Reviewer: Rifaat Shekh-Yusef Review result: Has Issues I have reviewed this document as part of the security directorate's ongoing effort to review all IETF documents being processed by the IESG. These comments were written primarily for the benefit of the security area directors. Document editors and WG chairs should treat these comments just like any other last call comments. "A backup egress MUST be configured on the ingress of an LSP to protect a primary egress of the LSP if and only if the backup egress is not indicated in another place." Can you define "another place"? Is it the "primary egress"? others? "To protect a primary egress of an LSP, a backup egress MUST be configured on the primary egress of the LSP to protect the primary egress if and only if the backup egress is not indicated in another place." Can you define "another place"? Is it the "ingress"? others? "Note that protecting a primary egress of a P2P LSP carrying service traffic through a backup egress requires that the backup egress trust the primary egress for the information received for a service label as UA label." Can you elaborate on this statement? How would the backup egress trust the primary egress? Regards, Rifaat
