Ticket 3: OSPF Authentication (QUESTION 61 ~ QUESTION 63)

Topology Overview (Actual Troubleshooting lab design is for below network design)

 

Client Should have IP 10.2.1.3

EIGRP 100 is running between switch DSW1 & DSW2

OSPF (Process ID 1) is running between R1, R2, R3, R4

Network of OSPF is redistributed in EIGRP

BGP 65001 is configured on R1 with Webserver cloud AS 65002

HSRP is running between DSW1 & DSW2 Switches

 

The company has created the test bed shown in the layer 2 and layer 3 topology exhibits.

This network consists of four routers, two layer 3 switches and two layer 2 switches.

 

In the IPv4 layer 3 topology, R1, R2, R3, and R4 are running OSPF with an OSPF process number 1.

DSW1, DSW2 and R4 are running EIGRP with an AS of 10. Redistribution is enabled where necessary.

R1 is running a BGP AS with a number of 65001. This AS has an eBGP connection to AS 65002 in the ISP’s network. Because the company’s address space is in the private range.

R1 is also providing NAT translations between the inside (10.1.0.0/16 & 10.2.0.0/16) networks and outside (209.65.0.0/24) network.

ASW1 and ASW2 are layer 2 switches.

NTP is enabled on all devices with 209.65.200.226 serving as the master clock source.

The client workstations receive their IP address and default gateway via R4’s DHCP server.

The default gateway address of 10.2.1.254 is the IP address of HSRP group 10 which is running on DSW1 and DSW2.

 

In the IPv6 layer 3 topology R1, R2, and R3 are running OSPFv3 with an OSPF process number 6.

DSW1, DSW2 and R4 are running RIPng process name RIP_ZONE.

The two IPv6 routing domains, OSPF 6 and RIPng are connected via GRE tunnel running over the underlying IPv4 OSPF domain. Redistrution is enabled where necessary.

 

Recently the implementation group has been using the test bed to do a `proof-of-concept’ on several implementations. This involved changing the configuration on one or more of the devices. You will be presented with a series of trouble tickets related to issues introduced during these configurations.

 

Note: Although trouble tickets have many similar fault indications, each ticket has its own issue and solution.

 

Each ticket has 3 sub questions that need to be answered & topology remains same.

Question-1 Fault is found on which device,

Question-2 Fault condition is related to,

Question-3 What exact problem is seen & what needs to be done for solution

Client is unable to ping IP 209.65.200.241

 

Solution

Steps need to follow as below:

When we check on client 1 & Client 2 desktop we are not receiving DHCP address from R4

Ipconfig —– Client will be receiving IP address 10.2.1.3

IP 10.2.1.3 will be able to ping from R4 , R3, R2 but not from R1

Check for neighborship of ospf

sh ip ospf nei —– Only one neighborship is forming with R2 & i.e. with R3

Since R2 is connected to R1 & R3 with routing protocol ospf than there should be 2 neighbors seen but only one is seen

Need to check running config of R2 & R3 for interface

Sh run ————————– Interface Serial0/0/0/0.12 on R2

Sh run ————————– Interface Serial0/0/0/0 on R1

Change required: On R1, for IPV4 authentication of OSPF command is missing and required to configure —— ip ospf authentication message-digest

 

QUESTION 61

The implementations group has been using the test bed to do a `proof-of-concept’ that requires both Client 1 and Client 2 to access the WEB Server at 209.65.200.241. After several changes to the network addressing, routing scheme, DHCP services, NTP services, layer 2 connectivity, FHRP services, and device security, a trouble ticket has been opened indicating that Client 1 cannot ping the 209.65.200.241 address. Use the supported commands to isolated the cause of this fault and answer the following questions. On which device is the fault condition located?

 

A.

R1

B.

R2

C.

R3

D.

R4

E.

DSW1

F.

DSW2

G.

ASW1

H.

ASW2

 

Correct Answer: A

Explanation:

On R1, for IPV4 authentication of OSPF the command is missing and required to configure —— ip ospf authentication message-digest

 

 

QUESTION 62

The implementations group has been using the test bed to do a `proof-of-concept’ that requires both Client 1 and Client 2 to access the WEB Server at 209.65.200.241. After several changes to the network addressing, routing scheme, DHCP services, NTP services, layer 2 connectivity, FHRP services, and device security, a trouble ticket has been opened indicating that Client 1 cannot ping the 209.65.200.241 address. Use the supported commands to isolated the cause of this fault and answer the following questions. The fault condition is related to which technology?

 

A.

BGP

B.

NTP

C.

IP NAT

D.

IPv4 OSPF Routing

E.

IPv4 OSPF Redistribution

F.

IPv6 OSPF Routing

G.

IPv4 layer 3 security

 

Correct Answer: D

Explanation:

On R1, for IPV4 authentication of OSPF the command is missing and required to configure —— ip ospf authentication message-digest

 

 

QUESTION 63

The implementations group has been using the test bed to do a `proof-of-concept’ that requires both Client 1 and Client 2 to access the WEB Server at 209.65.200.241. After several changes to the network addressing, routing scheme, DHCP services, NTP services, layer 2 connectivity, FHRP services, and device security, a trouble ticket has been opened indicating that Client 1 cannot ping the 209.65.200.241 address. Use the supported commands to isolated the cause of this fault and answer the following questions. What is the solution to the fault condition?

 

A.

Enable OSPF authentication on the s0/0/0 interface using the ip ospf authentication message-digest command

B.

Enable OSPF routing on the s0/0/0 interface using the network 10.1.1.0 0.0.0.255 area 12 command.

C.

Enable OSPF routing on the s0/0/0 interface using the network 209.65.200.0 0.0.0.255 area 12 command.

D.

Redistribute the BGP route into OSPF using the redistribute BGP 65001 subnet command.
