Document: draft-ietf-isis-auto-conf-04 Reviewer: Robert Sparks Review Date: 2017-04-07 IETF LC End Date: 2017-04-10 IESG Telechat date: 2017-04-13 Summary: Ready for publication as Proposed Standard, but with one possible thing to add to the security consideration section This document is clear and seems straightforward to implement. I think, however, there is an attack possibility you should call out in the security considerations section. As home routers are used as examples of elements that might use this protocol, consider the case of a malicious party wanting to deny service in that home. A suborned device in the home could watch for the protocol, and present a crafted packet to force the home router(s) to re-start the autoconfiguration protocol continually (by claiming to be a duplicate and being careful to make it the routers job to restart). Having the md5 password configured would mitigate this attack.
