Muliticast Routing Over ATM Link

Unanswered Question


I have a ATM link (45Mb/s) between 2 location . In one of my locations I multicast 4 diffrent Video traffic. But my 4 multicast traffic is going to the source router by 1 Fastethernet port and after that it's going to destionation over the ATM link. now I have an issue on destionation router . I need to seperate 4 multicasts traffic on the destionation router . it has to be  1 on of my multicast traffic going through VLAN 123 and the others 3 multicast traffics going through VLAN 200.

now all of the multicast traffic is going trough vlan 123.

any body can help me on this issue?

Hello Mike,

are vlan 123 and vlan 200 transit vlans on the remote site? or are they client vlans?

what unicast routing protocol are you using?

are you using PIM sparse mode?

Hope to help

Hello Mike,

may you describe the remote site design?

is something like:

site1 ---- R -------- ATM-E3 ------   R2 ----  vlan123,vlan200 --- switch --- client vlans, receivers here


site1 ---- R -------- ATM-E3 ------   R2 ----  vlan123,vlan200

with users in vlan 123 and vlan 200

because this makes the difference

Hope to help
