Lab#1
Network Learning, Inc. R&S CCIE Practice Lab 1 Version2.00 1-day Version
At the end of this lab verify connectivity to all ports. You should be able to ping every interface form any router. (don’t worry about being able to ping a local frame-relay interface. Please disregard this statement if you are asked to filter packets, routers or other specific tasks.)
1. Initial Configuration – 5 pts (30 minutes)
a. Use the pre-configuration files to apply proper IP addresses to the router interfaces. Add IP addresses as needed as shown on the network diagram.
b. Configure router R7 as a frame-relay switch. Refer to the diagram for interface connections to other routers connected to router R7.
c. Connect routers R1,R2, R3, and R5 over the frame-relay cloud. Configure router R1’s S0 interface as a sub-interface. Configure R2,R3, and R5 without using sub-interfaces. Use only one frame-relay PVC on routers R2, R3, and R5. The recommended DLCI numbers 102, 201,103,301,105, and 501 are indicated on the lab diagram.
d. Routers R1, R2, R3, and R5 should share network 10.10.x.x 255.255.0.0 on their frame-relay interfaces.
e. Router R1 should have network 10.1.x.x with an 8-bit subnet mask on its Ethernet interface( The mask should be 255.255.0.0)
f. Make sure all the Ethernet interfaces are in their own broadcast domain if you are using an Ethernet switch for your Ethernet connections.
2. OSPF Configuration –25pts (2 hours 30 minutes)
a. configure OSPF area 0 on the frame-relay interfaces between R1, R2, R3, and R5.
b. Configure router R1’s interface Ethernet 0 for OSPF area 1
c. Configure router R2’s interface E0 for OSPF area 10
d. Configure router R3’s interface S 1 and all of router R4’s interface for OSPF area 3.
e. Configure router R5’s interface E 0 for OSPF area 4.
f. Create two loopback interface on R4 and put both of the associated subnets on these interfaces in OSPF area 44.
g. Summarize the (2) loopback interface you just created on router R4 so they appear as one route to the rest of the OSPF routers in your network..
h. Here is the tricky part. You can’t use the command ip ospf network xxxx anywhere in your router configurations.
i. Redistribute the default route on router R2 as type-1 with a metric of 100. This route is already part of the initial configurations we provided for you.
j. Also, one of the problems in this lab can be solved with multiple frame map ip statements, but that is not the solution we want you to use, Solve the problem with routing, not layer 3 to layer 2 mapping via additional frame map statements!!!(Yes, this is a tricky issue)
You have completed lab 1. compare your configurations to the ones we provided. Often there is more than one complete a task so your configurations may be different than ours. If your configuration are different than ours make sure you understand how to complete the lab with our configurations too.
Lab 2
At the end of this lab verify connectivity to all ports. You should be able to ping every interface from and router. (Don’t worry about being able to ping a local frame-relay interface. Please disregard this statement if you are asked to filter packets. Routes or other specific tasks.)
1. Initial Configuration – 5 pts (30 mins)
a. Use the pre-configuration files to apply proper IP addresses to the router interfaces. Add IP addresses as needed as shown on the network diagram. You may have to add additional IP addresses to complete some tasks.
b. Connect routers R1, R2, R3, and R5 over the frame-relay cloud. Configure router R1 using sub-interfaces. Configure routers R2, R3, and R5 without using sub-interface.
c. Use only one frame-relay PVC on routers R2, R3, and R5, The recommended DLCI numbers 102,201,103, 301,105, and 501 for the frame-relay PVC’s are indicated on the network diagram.
d. Routers R1,R3,and R5 should share network 10.10.x.x 255.255.0.0 on their frame-relay interfaces
e. Routers R1 and R2 should share network 10.20.x.x 255.255.0.0 on their frame-relay interfaces.
f. Router R1 should have network 10.1.x.x with an 8-bit subnet mask on its Ethernet interface( The mask should be 255.255.0.0)
g. Router R2 should have network 137.20.20.0 with a 24-bit mask on its Ethernet interface.
h. Router R3 should have network 10.3.x.x with an 8-bit subnet mask on its token-ring interface ( The mask should be 255.255.0.0)
2. OSPF configuration –30 pts (2 Hours 30 minutes)
a. configure OSPF area 0 on the frame-relay interfaces between routers R1, R3 and Router R5.
b. Place router R1’s Ethernet in OSPF area 1. place router R5’s interface E0 in OSPF area 0.
c. Setup a default static route (default gateway) from R3 to R4. Redistribute this default static route into OSPF with a metric-type of 1 and a metric of 500.
d. Configure router R3’s serial 1 interface as 173.168.40.1/24 and router R4’s serial 0 interface as 172.168.40.2/24.
e. Configure router R4’s E0 interface as 200.100.100.1/24.
f. Configure a default gateway on router R4 to route all packets for which it has no routes to router R3.
g. Configure two loopback interfaces on router R3 with networks that could have at most 254 hosts and put them both in the same OSPF area, but different from OSPF area 0. Summarize this route into OSPF so that the two subnets appear as one route.
h. Configure router R2 for EIGRP and put all interface in the routing process.
i. Configure router R1 with EIGRP and redistribute with OSPF. Set the metric type to type-1 when you redistribute from EIGRP to OSPF. Also, redistribute OSPF into EIGRP.
j. Configure router R1 so that it only listens to EIGRP updates on E0 and S0.2.
k. Configure router R6 for OSPF with a different process ID than used thus far. Do not configure R6’s E0 for OSPF.
l. Configure router R8 to be in the same OSPF area as router R6. put router R8’s interface E0&Lo0 into the OSPF routing process. Configure router R6 so that its S1 interface speed is correctly reflected in the OSPF metrics without using the “ip ospf cost xxx” command.
m. Configure OSPF message-digest authentication between routers R6 & R8.
n. Change the OSPF hello interval between routers R6 & R8 to 45 seconds.
o. Configure router R8 suing the “ip ospf cost” command such that the speed of the link for interface S0 is correctly reflected in the OSPF metrics.
p. Change the OSPF transmit interval delay to 10 seconds between routes R6 & R8.
q. Add a default route to router R2 that points to 137.20.20.2. configure one static route on router R2 so that full connectivity to R4’s interface E0 is available. You will notice that the default gateway of router R2 has a lower administrative cost than the one learned via router R1. as a result, the other default route never makes it in the routing table for router R2.
r. You will notice that R2 can’t ping the serial interfaces between routers R3 & R4. fix this problem by only making changes to router R3 without static routes.
