[cisco-voip] Setting ip Multicast for MOH

[King, Jesse]

Only one hop,
 
source-----router-----router-----switch----phone
 
I found an interesting document, which pretty much lines it out, and I
have one site with it setup and working.
 
I'm using the following on the source router
 
ip multicast-routing
ip pim bsr-candidate FastEthernet0/0 30 1
 
interface fasteth 0/0
ip pim sparse-dense-mode
 
interface xxxx  to branch router
ip pim sparse-dense-mode
 
 
 
on the branch router
 
ip multicast-routing
interface fasteth 0/0
ip pim sparse-dense-mode
 
interface xxxx  to hq router
ip pim sparse-dense-mode
 
 
seems to be working okay.. Should I be limiting to just one group? I
think I am seeing multicasts from wireless accesspoints and a few other
devices for some reason.....

Hi Jesse, 

What is your goal with the Multicast MoH? 

Are you needing the Multicast traffic to go further than the directly
connected subnets?

	Okay - 
	I have 1760-v's in branches connected to 3550's. 
	On branch routers, in order to setup multicast routing 
	
	ip multicast-routing 
	and under the interface - serial? or fast eth? 
	
	ip pim dense-mode 
	Is this all I need, or do I need to set the router to be in a
particular group. We are not using multicast for anything else. 
	I am in the process of reading 'Configuring IP Multicast
Routing', and it says those two commands are required, others are
optional.. Is that really the case? and if so, which interface do I need
to have the ip pim set on, and is dense-mode the correct mode I should
be using? 
	Thoughts? 
	Thanks.
