F.Y.I. A flat network is a network in which all workstations are directly connected to each other, except for the presence of switches and can communicate without the need for intermediate devices such as Routers. A flat network is one without subnets,as a result,its topology is not divided into layers or modules.Every station on a flat network receives a copy of every message sent.Security is poor and it is not possible to establish alternative paths to destinations. But as the network is very huge we are using routers for communication. Thanks in advance.Your help will be appreciated. -- Akhil Nair =====-----=====-----===== Notice: The information contained in this e-mail message and/or attachments to it may contain confidential or privileged information.

Then I made t1 as source and t5 as receiver.I was able to get multicasted traffic in regular interval and mfc was also been added. But when I tried the reverse way i.e. t5 as source and t1 as receiver i got multicasted traffic once in 1 or 2 minutes.mfc was added in all the machines. I have also noted down one point that on t2 both the interfaces are DR but in all the other machines there is 1 DR and 1 Not DR condition.I also set the dr-priority then but then also no use, when i used same dr-priority as 1 in all the machines the same scene i found in t4 as eth0 and rename3 was both elected as DR.I think it happens because of the highest ip address. I have gone through the issues posted earlier but didn't found much help.I also read in some of the post that increasing the value of ttl will solve the issue.Is this issue can be solved by ttl increment ? In short my questions are : 1) Single side multicast forwarding is due to two DR's on one of the machine.I am using a flat network, its not a LAN. 2) Whether this issue can be solved by ttl increment. I am in much needy state and Help will be appreciated :) Thanks and Regards -- Akhil Nair =====-----=====-----===== Notice: The information contained in this e-mail message and/or attachments to it may contain confidential or privileged information.
