#FirstHopRedundancyProtocols Router Redundancy One way to prevent a single point of failure at the default gateway is to implement a virtual router. To implement this type of router redundancy, multiple routers are configured to work together to present the illusion of a single router to the hosts on the LAN. By sharing an IP address […]

Spanning Tree Path Cost

The interface STP cost is an essential component for root path calculation because the root path is found based on the cumulative interface STP cost to reach the root bridge. The interface STP cost was originally stored as a 16-bit value with a reference value of 20 Gbps. As switches have developed with higher-speed interfaces, […]

802.1D Port StatesIn the 802.1D STP protocol, every port transitions through the following states:■ Disabled: The port is in an administratively off position (that is, shut down).■ Blocking: The switch port is enabled, but the port is not forwarding any traffic toensure that a loop is not created. The switch does not modify the MAC […]

In the Answer Network panel, you construct the answer network, and mark the elements of the network on which you want to assess the students. Click on the Show Answer Network button to view the workspace for the answer network. If you chose to convert the existing workspace to the answer network when you first entered the […]

Se han desarrollado dos arquitecturas de red principales para admitir la virtualización de la red: •Redes definidas por software (SDN) : una arquitectura de red que virtualiza la red, ofreciendo un nuevo enfoque para la administración y administración de redes que busca simplificar y optimizar el proceso de administración. •Infraestructura centrada en aplicaciones (ACI) de […]

Before configuring SSH, the switch must be minimally configured with a unique hostname and the correct network connectivity settings Step 1 Verify SSH support. Use the show ip ssh command to verify that the switch supports SSH. If the switch is not running an IOS that supports cryptographic features, this command is unrecognized. Step 2 Configure the […]

FHRP Options

Tags: , , ,

The FHRP used in a production environment largely depends on the equipment and needs of the network. The table lists all the options available for FHRPs. Hot Standby Router Protocol (HSRP)HRSP is a Cisco-proprietary FHRP that is designed to allow for transparent failover of a first-hop IPv4 device. HSRP provides high network availability by providing […]
