[nsp] Speaking of Multicast

[Vincent De Keyzer]

Thanks again Kristofer,

it was not required (maybe it would be required with more than one
receiver).

All that was required was as below:

interface FastEthernet0/0.519
 description TV side
 encapsulation dot1Q 519
 ip address 10.30.50.1 255.255.255.0
 ip pim sparse-dense-mode
end

interface ATM2/0.800 point-to-point
 description Camera side
 bandwidth 10
 ip address 10.20.30.1 255.255.255.252
 ip pim sparse-dense-mode
 atm route-bridged ip
 pvc Camera 12/800
  vbr-nrt 8000 8000
  encapsulation aal5snap
 !
end

and of course, ip multicast-routing.

Thanks to all

Vincent
