Ballardie}, title = {{''shared-mtrace'': A Multicast 'traceroute' facility for Shared Trees}}, pagetotal = 7, year = 1997, month = oct, day = 27, abstract = {''mtrace'' {[}1{]} is a very useful tool for diagnosing IP multicast rout- ing problems, such as multicast routing loops and misconfigured mul- ticast routers, associated with source-rooted RPF-based distribution trees. For ''mtrace'' to be useful in a shared tree environment (e.g. PIM {[}2{]}, CBT {[}3{]}, GUM {[}4{]}) its behaviour must be modified. This draft speci- fies that behaviour, which is sufficiently general to be applicable to all shared tree types and operating modes. A new ''wildcard'' mode of behaviour is also described, which allows a trace of a complete shared tree. Authentication is recommended in this mode because of its potential as a vehicle for denial of service attacks. It is intended that this draft become a document of the Mbone Deploy- ment (mboned) working group of the IETF. Therefore, comments are solicited and should be sent to mboned's mailing list \textless{}mboned@network- services.uoregon.edu\textgreater{} and/or the author.}, }
