Proxy MPLS Echo Request
draft-ietf-mpls-proxy-lsp-ping-04
Abstract
This document defines a means of remotely initiating Multiprotocol
Label Switched Protocol Pings on Label Switched Paths. An MPLS Proxy
Ping Request is sent to any Label Switching Router along a Label
Switched Path. The primary motivations for this facility are first to
limit the number of messages and related processing when using LSP
Ping in large Point-to-Multipoint LSPs, and second to enable leaf to
leaf/root tracing.
