Multicast mtrace !

Sep 10, 2014 2 Replies

Hi Guys, Could u pls tell me the meaning of "none" in multicast mtrace? R6-Client#mtrace 10.0.12.1 Type escape sequence to abort. Mtrace from 10.0.12.1 to 10.0.56.6 via RPF From source (?) to destination (?) Querying full reverse path... 0 10.0.56.6



-1 10.0.56.6 None [10.0.12.0/24]



-2 10.0.56.5 None [10.0.12.0/24]



-3 10.0.45.4 None [10.0.12.0/24]



-4 10.0.24.2 PIM [10.0.12.0/24]



-5 10.0.12.1



I have already enable ip multicast-routing on global, PIM-SM on interface. Thanks so much ! Duong Vu.


Hello D??ng,

Do you see the PIM neighbours? It seems that field is meant to be the protocol in use on those links.

The documentations seems uniformly awful but perhaps a little wireshark and reference to

formatting link
which seems to be the genesis for mtrace could be revealing.

Hi Martin, Many many thanks for your reply. I use Iou Web to simulate this lab and I t hink problem here is iou web. When I use GNS3, the mtrace output is normal. again, thank you so much
