• Julho 4, 2023 O que é encaminhamento de caminho reverso Unicast (uRPF)? Uma rota padrão pode 0.0.0.0/0 ser usado para realizar uma verificação uRPF?
• Julho 4, 2023 Tenho quatro caminhos paralelos de custo igual para o mesmo destino. Estou ligando rapidamente dois links e processando a comutação nos outros dois. Como os pacotes serão roteados nesta situação?
• Julho 4, 2023 Is there a performance advantage when using the the IP access list keyword established on an extended ACL? Does using “established” make the access list more vulnerable? Do you have specific examples of the usage?
• Julho 4, 2023 I have primary and secondary IP addresses configured on an Ethernet interface and my router is running RIP (a distance vector routing protocol). How does split-horizon affect the routing updates?
• Julho 4, 2023 Is it possible to have duplicate ip addresses for two serial interfaces that belong to the same router?
• Julho 4, 2023 Can I configure two interfaces in the same subnet (t0 = 142.10.46.250/24 and t1 142.10.46.251/24)?
• Julho 4, 2023 Can an interface have more than one ip access-group statement in its configuration?
• Julho 4, 2023 Would it be possible to configure a router for a 255.255.254.0 Ethernet and a 255.255.252.0 serial subnet? Does IGRP/RIPv1 support variable subnetting?
• Julho 4, 2023 Does the interface subcommand no arp arpa disable the Address Resolution Protocol (ARP) function for a router interface?
• Julho 4, 2023 Does the use of extended IP access control lists (ACLs) filter regular routing updates (such as OSPF)? Do I need to explicitly permit the multicast IPs used by routing protocols (such as 224.0.0.5 e 224.0.0.6, in the case of OSPF) for updates to ensure the proper working of routing protocols?
• Julho 3, 2023 How do I configure my router to prefer an Open Shortest Path First (OSPF) route over an EIGRP route when the route is learned from both sources?
