The task is to design an architecture that distributes multicast traffic from location B to C. Location B currently subscribes and receives multicast traffic from location A.
Distance between B and C is around 290 miles (470 km).
The WAN service between B and C would be provided via GRE-Tunnel.
How easy/difficult is it to have the multicast traffic from location A subscribed to from location C or alternatively forwarded from location B to location C (If possible)?
Our thinking is simply to have a Layer 2/3 device acting as switch and router with PIM enabled on each interface.
Our other thinking is to have a VLAN-to-VLAN type connection between location B and C. Then all the PIM is handled by the interfaces at location B.
Is there a specific technical term for this type of connection?
Is this possible utilizing the GRE-Tunnel mentioned above or do we request another form of 'Tunnel'/Connection?
Thanks for any advice.
