Some probleme with the MVR protocol

Unanswered Question
Feb 13th, 2007


In order to broadcast some video on different VLAN, I use the MVR protocol on switch 2950 and 3560. This solution works, but I have some problemes when the switch reboot or when I do some intervention on the port (unblock an err-disabled interface, make a "no shut" for example). In those case, I must reactivate the MVR. The multicast flow reaches the switch, but the users can't access to it. I must write this sequence in configuration mode :

no mvr


When I write those instructions, everything works. This solution is OK if I have 1 switch, but not on an entire network. I don't understand why this protocol don't start correctly, like the others process.

To be more specific, the IOS version for the 2950 is IOS (tm) C2950 Software (C2950-I6Q4L2-M), Version 12.1(22)EA9.

I have this problem too.

A couple of things to check are

1- make sure pim is enabled on all subnets/vlans that has a client wishing to receive the stream.

2 - make sure that the ttl value on the application is high enough if it is crossing vlans.
