The Dynamic Trunking Protocol ( DTP) is a proprietary link layer protocol developed by Cisco Systems for the purpose of negotiating trunking on a link between two VLAN -aware switches, and for negotiating the type of trunking encapsulation to be used. VLAN trunks formed using DTP may utilize either IEEE 802.1Q or Cisco ISL trunking protocols. [ 1]
Router R1 is a one-armed router carrying out inter-VLAN routing. A router on a stick, also known as a one-armed router, [1] [2] is a router that has a single physical or logical connection to a network. It is a method of inter- VLAN routing where one router is connected to a switch via a single cable. The router has physical connections to the ...
VLAN Trunking Protocol. VLAN Trunking Protocol ( VTP) is a Cisco proprietary protocol that propagates the definition of Virtual Local Area Networks ( VLAN) on the whole local area network. [1] To do this, VTP carries VLAN information to all the switches in a VTP domain. VTP advertisements can be sent over 802.1Q, and ISL trunks.
Packet Tracer is a cross-platform visual simulation tool designed by Cisco Systems that allows users to create network topologies and imitate modern computer networks. The software allows users to simulate the configuration of Cisco routers and switches using a simulated command line interface. Packet Tracer makes use of a drag and drop user ...
Cisco Networking Academy. Cisco Networking Academy or NetAcad is an online global educational program product of American Cisco Systems. It started in California in 1997. [1] [2] [3] [4]
Virtual routing and forwarding. In IP-based computer networks, virtual routing and forwarding ( VRF) is a technology that allows multiple instances of a routing table to co-exist within the same router at the same time. One or more logical or physical interfaces may have a VRF and these VRFs do not share routes.
Developer (s) Cisco Systems. Introduction. 1994 [1] RFC (s) RFC1701, RFC1702, RFC2784. Generic Routing Encapsulation ( GRE) is a tunneling protocol developed by Cisco Systems that can encapsulate a wide variety of network layer protocols inside virtual point-to-point links or point-to-multipoint links over an Internet Protocol network.
Interlaken (networking) Interlaken is a royalty-free interconnect protocol . It was invented by Cisco Systems and Cortina Systems in 2006, [1] optimized for high-bandwidth and reliable packet transfers. It builds on the channelization and per channel flow control features of SPI-4.2, while reducing the number of integrated circuit (chip) I/O ...
