All things related to multicast

[Luís Marta <>]

Hi.

If one has a backbone network based on Fast/Gigabit Ethernet, different
brands of routers and not-so-powerful switches (no chance of running RGMP),
how does one implement multicast?
In order to avoid the multicast traffic to leak to all the switches' ports,
i thought of creating a separate VLAN to the multicast traffic, a VLAN that
connects the RP, the backbone routers until the last one before the client
(the access routers), but then the last connection may be ATM ou any other
technology.
As PIM interacts with the routing protocol in use (OSPF for example), how
can i make the multicast traffic that is supposed to go to a certain client
use the mentioned VLAN? Is there any other way of doing this without using
static mroutes to map the clients' routes? Because this is very
time-consuming and impossible to maintain.

Thanks in advance,

Luís Marta.
