The document discusses two types of ICMP messages received during a traceroute: 'port unreachable' and 'time exceeded'. It also addresses whether OSPF routes send link state information only to directly attached neighbors, confirming the statement as false because OSPF uses IP multicast for updates. This method minimizes processing on routers that are not focusing on OSPF packets.

- 1. 1. What two types of ICMP messages are received at the sending host executing the traceroute program? 2. True or false: When an OSPF route sends its link state information, it is sent only to those nodes directly attached neighbors. Explain. 1.

True or false: When an OSPF route sends its link state information, it is sent only to those nodes directly attached neighbors. Explain. Solution (1).The two types of messages are received at the srending host executing the traceroute programm is as follows: 1.Port unreachable 2.Time exceeded i.e TTL=0 (2).Answer:True Reason:it utilizes the IP multicast to send link state updates .it confirms little processing on routers which are not concentrating on OSF packets.
