For example there are some reports saying that Ethernet0/1 on R1 is shutdown (and this is the correct choice in the exam). So please be careful checking the config on the routers before choosing the correct answers.
- 2. pregunta 4 R3#show run R6#show run router ospf 6 no routerid 192.168.3.3 routerid 192.168.6.6 We are not sure about the configuration of ppp authentication in this case. Some reports said that only one router has the “ppp authentication chap“ command but it is just a trick and is not the problem here. The real problem here is R6 uses the same routerid of R3 (192.168.3.3) so OSPF neighborship cannot be established. In real life, such configuration error will be shown in the command line interface (CLI). So please check carefully for this question.
