Multicast Q

[saimbt]

I want to implement Multicast. Instead of a switch can I use a hud to connect 2 routers that are a part of a same multicast group?

here is my scenario

Router A --------- Router B -- Hub-- Router C

Router A and B are conneced through leased line.

I want to make router B and C a part of a same network, will a hub do or ONLY a switch is needed.

A hub will work, but of course all traffic on all hub ports is contending for the same bandwidth, so performance may suffer if you have other devices on the hub.

A switch configured for multicast would give better performance since the multicast, as well as unicast traffic, would only be sent out ports where needed.

Hi,

thank you for the quick response....

the hub would be dedicated for the multicast traffic

only 2 ports would be used.. 1 for router B and the other for router C

In that case you could use a crossover ethernet cable to connect the routers directly.

The point of having a switch usually would be that it would be VLAN 802.11q aware, and take care of VLAN tagging.

If you use a hub, if you're running 802.11q VLANs, the NICs will have to be 802.11q aware.

If it's vanilla ethernet, then Bob's your uncle.
