Re: [OSL | CCIE_Voice] ip pim dense mode

[Peterson, Ryan]

you would not want that command.  it wouldnt matter if you had it since you 
would have had to enable multicast routing, but if you accidently did that, 
then the user could hear both CUCM and flash audio streams on their phone at 
the same time.

You would however need it if you were sourcing MOH from CUCM as multicast and 
trying to hop a layer 3 boundry.

Of course, Im not a big fan of using multicast routing in dense mode (in 
production).  Id probably setup RPs and Sparse mode.

Re: [OSL | CCIE_Voice] ip pim dense mode

[Rogers Ochieng, CCIE #28970]

You actualy don't need pim dense mode when route in below command

*multicast moh** multicast-address* *port* *port* [*route* *ip-address-list*]


route ip-address-list—(Optional) Declares the IP address or addresses from
which the flash MOH packets can be transmitted.

Hi Danny,

You are configuring CUCM to multicast MOH and fooling the router by 
multicasting MOH locally on the same IP / port. (Trick behind MOH from 
flash)


For the interfaces to forward multicast request you need "ip pim dense 
mode" command, specifically on voice vlan interface, else phones will 
not get MOH because you are multicasting MOH on flash. (even applies if 
you are using CUCM MOH, need additional interfaces to be configured for 
"ip pim dense mode" and hops)


Hope this helps

Because we did not pass any multicast traffic, so why bother to put

hi all,

for MOH from  router flash, why we ever need this command " ip pim dense
mode" on router and swith interface.

Because we did not pass any multicast traffic, so why bother to put this
command ?
