	In the current session the exam paper has five questions. It is SIMILAR in approach to the Semester 1 exam. You should complete any three from five questions. The main areas are: 1.rpcinfo, rpcbind, NFS, NIS [J.Jackson] rpcinfo, rpcbind, NFS, NIS.   2. Encryption [J.Jackson] Public-key principles. Key pairs (E,n and D,n).   3.Routing Configuration [W.Buchanan] Basic route programming (set-up login, network protocols, etc). ACLs.   4. Routing Protocols [W.Buchanan] Distance vector v. Link state. Setting up routing protocols (such as RIP) for networks with a defined subnet mask, and port IP address. Restricting routing information on links.   5. NDS [W.Buchanan] Structure of NDS. Fault tolerance of NDS. Context (CX) in NDS.

Trying to study for the NOS on Fri but struggling to find anything on "setting up routing protocols for networks with a definited subnet mask, and port IP address and restriciting routing information on links.

You use the emulator to practice setting up routing protocols. To restrict the transmission of routing informaton you leave the network address out of the routing configuration.

For example:

IF a network connects to the networks 192.168.10, 168.10.30.0 and 10.10.0.0, and you want to restrict the routing protocols to the first two network, you program with:

config t
router rip
network 192.168.10.0
network 168.10.30.0
exit
exit

The zero address is important as it defines the network portion. For example if a port has the address of 192.168.10.131 and the subnet mask is 255.255.255.128, then the subnet address on which it connects will be 192.168.10.128 as the most-significant bit in the last field identifies the network portion.
