Subnets and RIP-2

Make the internetwork of figure chap15.png

Don't turn on routing protocol until after the questions below are answered.

Add a NM-1-CFE module to powered-down Switch 3 to get Fa6/1.

Subnet numbers of the serial links between the routers:
R1-R2 192.168.1.0/30
R1-R4 192.168.1.12/30
R3-R2 192.168.1.4/30
R3-R4 192.168.1.16/30

Subnet numbers of the Ethernets:
R1 Fa0/0 10.10.24.0/21
R1 Fa1/0 10.10.8.0/21
R3 Fa0/0 172.31.5.0/25
R2 Fa0/0 192.168.4.16/28  this is same as R4 Fa0/0

Assign the router Ethernet interface the first host address of its
subnet (exception: R4's Ethernet interface is to be the 
second host address of its subnet, since it shares that Ethernet with R2).

Assign the LAST host address of each subnet to the PCs. (or
the second-to-last or thrid-to-last for the excess PCs).

The default gateway of PC4 and PC5 is R2.
The default gateway of PC6 is R4.

On a printout of the figure, write down the interfaces' IP addresses.

Before turning on the routing protocol, can PC6 ping
PC5 _____
R4 Fa0/0 _____
R4 S3/0  _____
R4 S2/0  _____
R2 Fa0/0 _____
R2 S2/0  _____
R2 S3/0  _____
R3 S2/0  _____



RIP (version 1, aka RIP-1) can't deal with subnets, so RIP-2 
(RIP version 2) was developed.  RIP-2 configuration is the same 
as RIP-1 except a "version 2" subcommand is included.  The "network"
subcommands still must only be classful networks, i.e. do not
specify subnet numbers.
Hint: each of our routers is connected to only two classful networks
as far as RIP is concerend, so each router needs only two "network"
Now configure RIP-2 on routers R1 and R4 only.
What new networks does R1 now know about:_________________________
What new networks does R4 now know about:_________________________
Is R4 aware of the subnetting of the 10.0.0.0 network:______
Can PC6 now ping:
R2 S2/0  _____
R2 S3/0  _____
What is the path a packet from PC6 takes to R2's S2/0:
_____________________________________________
What is the path a packet takes from R2 to PC6:_______________


After convergence,
Paste the routing table of R3:





Paste the tracert from PC3 to PC0:



Paste the tracert from PC6 to R2's S2/0:
