  2. Change from -12 • Add a new section: 9.2. Filtering of Clients • Comment raised by John Kristoff • There is only a brief mention of the potential for amplification of responses and no detailed analysis to the extent, including no mention of the susceptibility to it from spoofed requests. • Perhaps it would be sufficient if the LHR had to ensure a client issuing an Mtrace2 Query can receive a response.

  3. New: 9.2. Filtering of Clients • A router SHOULD support a mechanism to filter out queries from clients beyond a specified administrative boundary. Such a boundary could, for example, be specified via a list of allowed/disallowed client addresses or subnets. If a query is received from beyond the specified administrative boundary, the Query MUST NOT be processed. The router MAY, however, perform rate limited logging of such events.

  4. Old: 4.1.1. Query Packet Verification • Mtrace2 supports a non-local client to the LHR/RP. It is up to the implementation to filter out such queries.

  5. New: 4.1.1. Query Packet Verification • Mtrace2 supports a non-local client to the LHR/RP. A router SHOULD, however, support a mechanism to filter out queries from clients beyond a specified administrative boundary. The potential approaches are described in Section 9.2.

  6. Next Step • Ready for WGLC? • (We’ll revise the draft with small changes and submit it within a few days unless no other changes required)
