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 […]

Basic Router Configuration Review

Verification Commands Common verification commands include the following: •show ip interface brief •show running-config interfaceinterface-type number •show interfaces •show ip interface •show ip route •ping In each case, replace ip with ipv6 for the IPv6 version of the command.

Build the Routing Table

Directly Connected Networks: Added to the routing table when a local interface is configured with an IP address and subnet mask (prefix length) and is active (up and up). Remote Networks: Networks that are not directly connected to the router. Routers learn about remote networks in two ways: •Static routes – Added to the routing table when […]

Types of OSPF Packets

Posted: 5th June 2020 by ccna7guru in SRWE

Link-state packets are the tools used by OSPF to help determine the fastest available route for a packet. OSPF uses the following link-state packets (LSPs) to establish and maintain neighbor adjacencies and exchange routing updates. Each packet serves a specific purpose in the OSPF routing process, as follows: Type 1: Hello packet – This is used […]

MAC Address Table

Posted: 21st April 2020 by ccna7guru in SRWE

The MAC address table is responsible for identifying the switch ports and VLANs with which a device is associated. A switch builds the MAC address table by examining the source MAC address for the traffic that it receives. This information is then maintained to shrink the collision domain (point-to-point communication between devices and switches) by […]
