Hi Pavel obviously not, as you see from previous email market is connected to an ASR. then there is a C6807 and the only customer currently requesting this huge mcast feed is connected to C6500 with a WAN link...
I've attached my hw configuration, facing my cisco knowledge it shouldn't be an issue, but I was asking for hints... Matt has pretty confirmed it should work, but he is not sure about the overall quality if I get it well, if you have another view please let me know.
