Hi Mark,
Thanx,great explanation, but how HQ should know to send multicast traffic via it's loopback ? (in CME setup there is a commnad to tell router to do that but there is no telephony-service on this router) now I get IP(0): s=142.4.64.11 (FastEthernet0/0.11) d=239.1.1.5 id=59691, ttl=4, prot=17, len=214(200), mroute olist nul on HQ router Jeremy On Mon, May 18, 2009 at 4:44 AM, Mark Snow <[email protected]> wrote: > Loopback on HQ rtr also needs ip pim sparse-dense or dense-mode depending > on how you have multicast setup.
