L2TP Tunnel Switch

L2TP tunnel switching, also known as L2TP multihop, simplifies the deployment of an L2TP network across multiple domains. A router that lies between a LAC and an LNS is configured as an L2TP tunnel switch (LTS)---sometimes referred to simply as a tunnel switch or a tunnel switching aggregator (TSA). The LTS is configured as both an LNS and a LAC. When a remote LAC sends encapsulated PPP packets to the LNS configured on the LTS, the LTS can forward or redirect the packets through a different tunnel to a different LNS beyond the LTS. The logical termination point of the original L2TP session is switched to a different endpoint.\
