Homework 2a GNS3 Due September 30
2a GNS3 Homework代写 (Completing Configuration 30 points)Using the GNS3 emulation configure the network architecture shown in the drawing below.
(Completing Configuration 30 points) Using the GNS3 emulation configure the network architecture shown in the drawing below. Routers R1- R8 are running OSPF routing protocol. Router R9 is running routing protocol RIP. All loopbacks in routers R1- R8 should be configured as loopback0.
1. (10 points) 2a GNS3 Homework代写
You may verify the ospf configuration by pinging any loopback in routers R1-R8 from any other ospf router.
a. Attempt to ping any loopbacks associated with R9 from R1. The attempt should fail. To investigate the reason, do a sho ip route on R1. Explain the route entry designations (O and OIA) in the table.
b. There are no loopback entries for the loopbacks on R9 in the R1 routing table. Why are they not there and what is the solution?
2. (5 points)
Configure RIP on the redistribution router and configure redistribution on the router using the following command under the ospf process
redistribute rip metric 15 subnets
a. Verify the success of redistribution by doing a sho ip route on R1. Document the table (document means to do a screen shot or copy and paste).
b. Explain the designation of E2 in the routing table. What is the cost of the E2 entries in the table and explain the cost.

Ping a loopback address in the table (remember the .1). What is the result?
a. There is still a problem even though the network is listed in the route table. To determine the problem apply wireshark to the link between R8 and R9 (put the cursor on the link and right click selecting packet capture) and do the ping again.
b. What is the source ip and destination ip of the echo request?
c. Is there an echo reply? What must the source and destination of the echo reply be?
d. Go to R9 and configure a default static route.
e. Document the static route in R9 by doing a sho ip route and document the results.
f. Start the packet capture again and repeat the ping.
g. Document the results.
4. (10 points)
Return to R8 and change the redistribution under the ospf configuration to:
a. redistribute rip metric 15 metric-type 1 subnets
b. Do a sho ip route on R1 and document the results.
c. Explain the change in entry from E2 to E1 and the change in cost. (Note you may have to do a sho interface on some routers which may be running interfaces at 10 Mb/s rather than 100 Mb/s).
5. (15 points) 2a GNS3 Homework代写
On routers R6 and R8 modify the ospf configuration as shown:
a. area 20 nssa
b. Do a sho ip route on R6. Based on the route table what type of lsas are being advertised in area 20?
c. Do a sho ip route on R7. Explain the results (Hint do sho ip ospf neighbor, and show ip ospf data base)
d. What is the problem? How do you correct the problem? (Hint: modify the ospf config to the same area type.
e. After correcting the problem do a sho ip route on R7. Document the results.
6. (15 points)
Do a sho ip route on R1
a. Document the results
b. Make area 15 a stub area do a sho ip route on R1 document and explain the results.
c. Make area 15 a totally stubby area. Do a sho ip route on R1 document and explain the results.
