[cisco-voip] Multicast issue

[Scott Voll]

I found out from the vendor it's 224.255.255.253 and did a sh ip mroute.  it
looks like on my Cat 6509 it's routing to the wrong vlan...... I have a TAC
case open and I think it's either a MLS issue or a bug.  I will see when the
TAC engineer gets back to me.

Thanks

Scott
