The LAC may determine, based on the indication, a multicast address associated with initiating setup of the L2TP tunnel. The LAC may provide, to the multicast address, a request associated with initiating the L2TP tunnel. The request may be provided such that a plurality of L2TP network servers (LNSs) receives the request. The LAC may receive a set of responses to the request. The set of responses may be provided by a respective set of LNSs. The plurality of LNSs may include the respective set of LNSs. The LAC may select, based on the set of responses, a particular LNS, of the respective set of LNSs, with which to set up the L2TP tunnel."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Using a multicast address as a tunnel remote gateway address in a layer 2 tunneling protocol access concentrator","description":"A layer 2 tunneling protocol access concentrator (LAC) may receive an indication to set up a layer 2 tunneling protocol (L2TP) tunnel.
