摘要：
Techniques are described which facilitate multi-destination forwarding in a Layer 2 Multipath (L2MP) network which includes an emulated switch. The emulated switch may correspond to two or more underlying peer link switches in the L2MP network, in which each of the peer link switches is linked to a Classical Ethernet (CE) switch over a virtual port channel (vPC). Traffic received by one of the peer link switches over the vPC is automatically forwarded to the other peer link switch (or switches). Multi-destination frames originating from the L2MP network addressed to hosts within the CE network are sent over only one of the peer link switches.
