Glossary IETF IGMP Internet Internet Protocol (IP) IRB IP ISO ISP ITU-T Internet Engineering Task Force. Task force consisting of over 80 working groups responsible for developing Internet standards. Internet Group Management Protocol. Used by IP hosts to report their multicast group memberships to an adjacent multicast router. A collection of networks interconnected by a set of routers that allow them to function as a single, large virtual network. The network layer protocol for the Internet protocol suite. Integrated routing and bridging. A protocol that allows a router to act as both bridge and router on the same interface. For broadband aggregation, we recommend using the routed bridge encapsulation (RBE) protocol. See RBE. See Internet Protocol. International Standards Organization. A voluntary, non-treaty organization founded in 1946, responsible for creating international standards in many areas, including computers and communications. Internet service provider. A company that allows home and corporate users to connect to the Internet. International Telecommunications Union, Standardization Sector. ITU-T is the telecommunication standardization sector of ITU and is responsible for making technical recommendations about telephone and data (including fax) communications systems for service providers and suppliers. L L2F L2TP LAC LAN LCP Layer 2 Forwarding. Protocol that supports the creation of secure virtual private dial-up networks over the Internet. Layer 2 Tunnel Protocol. An Internet Engineering Task Force (IETF) standards track protocol defined in RFC 2661 that provides tunneling of PPP. Based upon the best features of L2F and PPTP, L2TP provides an industry-wide interoperable method of implementing VPDN. L2TP access concentrator. A node that acts as one side of an L2TP tunnel endpoint and is a peer to the L2TP network server (LNS). The LAC sits between an LNS and a remote system and forwards packets to and from each. Packets sent from the LAC to the LNS requires tunneling with the L2TP protocol as defined in this document. The connection from the LAC to the remote system is either local or a PPP link. Local area network. A limited distance (typically under a few kilometers or a couple of miles) high-speed network (typically 4 to 100 Mbps) that supports many computers. Link control protocol. Protocol that establishes, configures, and tests data-link connections for use by PPP. OL-2226-23 Cisco 10000 Series Router Software Configuration Guide GL-5
