Conventional network packet traffic loss/drop monitoring mechanisms, such as that employed for pseudowire, IP flow and tunnel traffic monitoring, do not process or diagnose the aggregate counts from both endpoints of a particular pseudowire. Illegal packet: IPv4 (protocol 41) + IPv6 (hop limit = 100) + ICMPv6 Router Advertisement. This adds complexity and means that unicast is using a different forwarding mechanism than multicast, which is not the optimal solution. In computer networking, Layer 2 Tunneling Protocol (L2TP) is a tunneling protocol used to support virtual private networks (VPNs) or as part of the delivery of services by ISPs. example RFC.
