Summary

In this chapter, we examined the basics of routing in the Solaris environment. Since routing underlies all remote packet delivery, it's important for administrators to understand the complex processes involved, especially the configuration of firewalls.

Questions

1.	Which three major types of subnet are supported by Solaris? Class 1, Class 2, Class 3 Class A, Class, Class C T1, broadband, cable None of the above
2.	What is the purpose of a router? To pass information from one network to another To pass information between two hosts only To provide two independent network interfaces on a single host None of the above
3.	What is the main requirement of a router? To be connected to the Internet To run Solaris 8 To have multiple network interfaces None of the above
4.	What would be contained in the file /etc/hostname.hme0 (choose two)? A hostname A fully qualified domain name An IP address The default router's hostname
5.	What is contained in the file /etc/defaultrouter ? The local router's hostname The local router's IP address The local router's hostname or IP address The local router's netmask
6.	What file should be created for a nonrouting, multihomed host? /etc/noroute /etc/notrouter /etc/notroute /etc/!route
7.	What command is used to set parameters for network protocols? tcp ip tip ndd
8.	What command is used to display parameters for network protocols? tcp /dev/tcp \? ip /dev/tcp \? tip /dev/tcp \? ndd /dev/tcp \?
9.	What command is used to trace a network route? net route trace -route traceroute net -route
10.	What protocol does rdisc use? ICMP router discovery protocol RTD router discovery protocol RDP router discovery protocol RDSC router discovery protocol
