Esercizio 1: Stateless configurationGiven the configuration in the figure,assuming that Router Advertisement isenabled only in R1, which <strong>IPv6</strong> addressesare obtained by the host interface withstateless configuration?R1InternetR22001:1:0:1::1/64 2001:1:0:7::1/64HostPossible answers:A) 2001:1:0:1:20b:5dff:fe4c:3a6b, 2001:1:0:7:20b:5dff:fe4c:3a6b, fe80::20b:5dff:fe4c:3a6bB) 2001:1:0:1:20b:5dff:fe4c:3a6b, fe80:1::20b:5dff:fe4c:3a6bC) 2001:1:0:7:20b:5dff:fe4c:3a6b, fe80::20b:5dff:fe4c:3a6bD) 2001:1:0:1:20b:5dfe:ff4c:3a6b, fe80::20b:5dff:fe4c:3a6bE) 2001:1:0:1:20b:5dff:fe4c:3a6b, fe80::20b:5dff:fe4c:3a6b2
AnswerA) Wrong, because R2 does not send Router Advertisement messages,and the prefix 2001:1:0:7::/64 cannot be configured in the host.B) Wrong, because the link local prefix is wrong (FE80:1::/64, while itshould be FE80::/64)C) Wrong, because the global address has a prefix derived from R2,which does not advertize it.D) Wrong. The public <strong>IPv6</strong> address is valid, but the interface ID isincorrectly obtained from the MAC address (note that the two bytesFF and FE are misplaced). Since we assume stateless configuration,the address is wrong.E) Correct.3
