All things related to multicast

[Arturo Lev Servin <>]

Hi,

	We are supposed (Tec de Monterrey, Mexico) to recieve a 
multicast session from Spain. In Spain they recieve the multicast 
session with out problem between the Spanish Universitues. In Mexico 
I can see and recieve the session from Oregon for example, but not 
from the Spanish.

	I suppose that there is not multicast connectivity between 
Geant and Iris (European and Spainish networks) or between Abilene 
and Geant.

	Any body knows if between Abilene and Geant exist multicast 
connectivity?

        The multicast group they gave me is: (193.146.115.212, 227.142.142.3)

	Another thing is that we have asymetric path in unicast. My 
unicast traffic goes from CUDI (Mexico) to VBNs to Abilene to geant. 
From Spain they go to Geant to Abilene and then directly to CUDI 
without passing VBNs. Could be this asymetric path another problem?

Thanks in advance,
