In Layer 2 Protocol Tunneling (L2PT), the device rewrites the original multicast destination MAC address of the packet. The packet then travels across the provider network transparently to the other end of the tunnel, where the destination device restores the original multicast destination MAC address. By default, the device rewrites the multicast destination MAC address with the predefined multicast tunneling MAC address 01:00:0C:CD:CD:D0 in the MAC table. You can optionally specify a different multicast MAC address.
To specify the MAC address, use the tunnel-destination-mac mac-address statement at the [edit protocols layer2-control layer2-control mac-rewrite] hierarchy level. You can set any non-reserved multicast MAC address.
