How LLDP Works, LLDP Mechanism

LLDP (Link Layer Discovery Protocol) LLDP (Link Layer Discovery Protocol) is a Standard Neighbour Discovery Protocol that is used by all vendors. Like all other Neighbour Discovery Protocols, LLDP works on Layer 2 (Data-link Layer). By using LLDP, directly connected neighbours are discovered. To discover a neighbour device, LLDP must be enabled both on the […]

Neighbour Discovery Protocols Neigbour Discovery Protocols provides directly connected devices to discover and collect information about each other. Network devices can provide directly connected neighbour device’s identification, configuration and any capabilities. Neighbour Discovery Protocols work on Layer 2. There are different neighbour protocols for different vendors. Generally they are refer this protocol like “vendor” discovery […]

redundancy protocols VRRP (Virtual Router Redundancy Protocol), protocols for redundancy

VRRP(Virtual Router Redundancy Protocol) VRRP(Virtual Router Redundancy Protocol) is a standard based redundancy protocol. The configuration of this protocol is like HSRP with only small differences. In VRRP the active router is called Master, and the remainning ones are all Backup routers. So there can be multiple backup routers. VRRP (Virtual Router Redundancy Protocol) By […]

network redundancy, protocols for redundancy

Network Redundancy Protocols Redundancy is a common point for today’s topologies. Especially in mission-critical networks it is not acceptible that using only one gateway to reach a point. Because one gateway means single point of failure. With multiple gateways, you can still reach the remote node even if the gateway that you connect fails. As […]

vlan frame tagging protocols, ISL and Dot1q

DTP (Dynamic Trunking Protocol) and VLAN Frame Tagging Protocols (ISL and dot1.q) LAN Frame Tagging Protocols (ISL and dot1.q) There are two types of frame tagging protocols. These are : – ISL(Inter-Switch Link) – dot1Q (or IEEE 802.1Q) These protocols can be configured manually or negotiated by DTP(Dynamic Trunking Protocol). DTP is a Cisco proprietary […]
