I doubt that this is a bandwidth issue because unless you have some sort of
QoS for your multicasting, the news simply doesn't get dropped over the
price update. The 3 minute time limit when the news traffic drops sounds

Can anyone shed some light on this problem?
We are doing remote WAN multicast under a PIM Auto-RP environment. The
remote Xtra3000 client will stop updating the News within 3 mins from

Looks like multicast is working

My guess is that you don't have the phrase quite right. :-) It'
"L3 to L2 mapping": how does a multicast IP address translate to a MAC
address.
"link-local": 224.0.0.1-224.0.0.255
"link-local L3 to L2 mapping": how to translate the IP addresses in the
range 224.0.0.1-224.0.0.255 to MAC addresses.
At least that's my guess.

Hi,
I have some users who want to use a multicast application between different
vlans.
Is multicast forwarding turned on by default on 12.1 IOS? Would'nt I need to
config
something like PIM, IGMP and CGMP on my cat's and routers to do this
efficiently
or will the IOS just flood multica

Hi all,
I am using a Cisco Cat.2950 switch to connect the network. Assume I have 5
computers are connected to the switch. 3 of them will tell using multicast.
I don't want the other computers listen this multicast. How can I control
only these three switch ports can send and receive
Hi all,
I would like to share the way I am implementing QoS in a 6509 switch to deal
with video multicast presentation.
It will be great to receive your thoughts and experience, concerning
Multicast application used and QoS solution.
The multicast application is Window Media Server and the

Hi Paul,
To configure a router to be an Auto-RP use the following command:
Router(config)# ip pim send-rp-announce
scope
This should be applied on both R1 & R2 in your scenario.
To configure a router a RP mapping agent (R4 in your scenario) use
n to 224.0.1.40 to determine which RP to use.
Kindly let us know if this will work out or not as I am not that strong
with Multicast and it happens for me to be studying it now so I looked
for the commands but never tried it myself.

Yasser

Hi,
If you have control over the TTL of the multicast packets, you can make
use of the TTL threshold interface command (ip multicast ttl-threshold).
For instance, set a threshold of 15 on Serial0/3. Multicast packets with
a TTL lower than 15, will not be forwarded out that interface. Now

s a common question. Ultimately, the best advice I've ever received
is: "If in doubt, read the RFC."

Hi
I have a question regarding the election of the LAN router which is supposed
to send the queries for multicast accesses.
In chapter 8, page 302, IGMPv2 querier election, it is mentioned that the
router with the lowest IP address is elected as multicast querier. In
Chapter 9, page 336, it is
