13. HSRP Case You have been asked by your customer to help resolve issues in their routed network. Their network engineer has deployed HSRP. On closer inspection HSRP doesn't appear to be operating properly and it appears there are other network problems as well. You are to provide solutions to all the network problems.
You have received notification from network monitoring system that link between R1 and R5 is down and you noticed that the active router for HSRP group 1 has not failed over to the standby router for group 1. You are required to troubleshoot and identify the issue. A. There is an HSRP group track command misconfiguration B. There is an HSRP group priority misconfiguration C. There is an HSRP authentication misconfiguration D. There is an HSRP group number mismatch E. This is not an HSRP issue; this is routing issue. Answer: A Explanation: When looking at the HSRP configuration of R1, we see that tracking has been
enabled, but that it is not tracking the link to R5, only the link to R2:
R1 should be tracking the Eth 0/1 link, not 0/0 to achieve the desired affect.
14.The following debug messages are noticed for HSRP group 2. But still neither R1 nor R2 has identified one of them as standby router. Identify the reason causing the issue. Note: only show commands can be used to troubleshoot the ticket. R1# 'Mar 26 11:17:39.234: HSRP: Et1/0 Grp 2 Hello out 172.16.20.2 Active pri 100 vIP 172.16.20.254 'Mar 26 11:17:40.034: HSRP: Et0/0 Grp 1 Hello out 172.16.10.2 Active prj 130 vIP 172.16.10.254 R1# 'Mar 26 11:17:40.364: HSRP: Et0/0 Grp 1 Hello in 172.16.10.1 Standby pri 100 vIP 172.16.10.254 R1# 'Mar 26 11:17:41.969: HSRP: Et1/0 Grp 2 Hello out 172.16.20.2 Active pri 100 vIP 172.16.20.254 172.16.20.254 'Mar 26 11:17:53.338: HSRP: Et0/0 Grp 1 Hello out 172.16.10.2 Active pri130vlP 172.16.10.254 'Mar 26 11:17:53.633: HSRP: Et0/0 Grp 1 Hello in 172.16.10.1 Standby pri 100 vIP 172.16.10.254 A. HSRP group priority misconfiguration
B. There is an HSRP authentication misconfiguration C. There is an HSRP group number mismatch D. This is not an HSRP issue: this is DHCP issue. E. The ACL applied to interface is blocking HSRP hello packet exchange Answer: E Explanation: On R1 we see that access list 102 has been applied to the Ethernet 1/0 interface:
This access list is blocking all traffic to the 224.0.0.102 IP address, which is the multicast address used by HSRP.
15.Examine the configuration on R4. The routing table shows no entries for 172.16.10.0/24 and 172.16.20.0/24. Identify which of the following is the issue preventing route entries being installed on R4 routing table? A. HSRP issue between R4 and R2 B. This is an OSPF issue between R4 and R2 C. This is a DHCP issue between R4 and R2 D. The distribute-list configured on R4 is blocking route entries E. The ACL configured on R4 is blocking inbound traffic on the interface connected to R2
Answer: D Explanation: If we look at the configuration on R4 we see that there is a distribute list applied to OSPF, which blocks the 172.16.20.0/24 and 172.16.10.0/24 networks.
16.Examine the configuration on R5. Router R5 do not see any route entries learned from R4; what could be the issue? A. HSRP issue between R5 and R4 B. There is an OSPF issue between R5and R4 C. There is a DHCP issue between R5 and R4 D. The distribute-list configured on R5 is blocking route entries E. The ACL configured on R5 is blocking traffic for the subnets advertised from R4. Answer: C Explanation: R5 configuration: int gig0/0 ip address dhcp This interface not getting dhcp ip address from R4. So even though OSPF configuration was like 0.0.0.0 0.0.0.0 area 0, because this interface does not get correct ip address from DHCP it can’t participate in OSPF. R4 configuration:
ip dhcp exlude address ip dhcp pool ine network x.x.x.x x.x.x.x i think default router command was missing here. not sure but Int gig0/0 ip address dhcp. This interface on R4 should have ip address configured on it instead of� ip address dhcp�. Hence its not able to provide dhcp lease address to R5. R4 also had ospf configured as network 0.0.0.0 0.0.0.0 area 0. So all interface can participate if they are up and if they have ip address. But because R5 interface connected to R4 could not obtail correct dhcp ip address from R4 due to DHCP issue they wont form ospf neighborship. So correct answer is DHCP issue between R5 & R4.
17. BGP sim
Answer:
18. Trouble&Shooting 16 TT generic topologies. Each TT topology is the same, but the configuration is different. 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 BGPAS 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 andASW2 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.
19. Ticket 1 OSPF Authentication TROUBLE TICKET STATEMENT: “The implementation group has been using the test bed to do a ‘proof-of-concept’ that required both client 1 and client 2 to access the Web Server at 209.65.200. 241. After several changed to interface status, network addressing, routing schemes and layer 2 connectivity, at trouble ticket has been opened indicating that client 1 cannot ping the 209.65.200.241 (internet Server)” The following information needs yourself show run: Configuration of R1: interface Serial0/0/0 description Link to R2 ip address 10.1.1.1 255.255.255.252 ip nat inside encapsulation frame-relay ip ospf message-digest-key 1 md5 TSHOOT ip ospf network point-to-point ! router ospf 1
router-id 1.1.1.1 log-adjacency-changes network 10.1.2.0 0.0.0.255 area 12 network 10.1.10.0 0.0.0.255 area 12 default-information originate always ! Configuration of R2: interface Serial0/0/0.12 point-to-point ip address 10.1.1.2 255.255.255.252 ip ospf authentication message-digest ip ospf message-digest-key 1 md5 TSHOOT ! On which device is the fault condition located? A. R1 B. R2 C. R3 D. R4 E. DSW1 F. DSW2 G. ASW1 H. ASW2 Answer: A Explanation: As you will see, the problem in this situation is with OSPF on R1. It is missing the "ip ospf authentication message-digest" command on the Serial0/0/0/0.12 interface.
20.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 Answer: D Explanation: The problem in this situation is with OSPF on router 1. It is missing the "ip ospf authentication messagedigest" command on the Serial0/0/0/0.12 interface. The problem statement tells us that the two routers are not able to become OSPF neighbors.
21. What is the solution of the fault condition? A. enable OSPF Authentication on the S0/0/0 interface using the ip ospf authentication messagedigest command B. enable OSPF routing on the s0/0/0 interface using the network 10.1.1.0 0.0.0.0.255 area 12 command C. enable OSPF routing on the s0/0/1 interface using the network 209.65.200.0 0.0.0.255 area 12 command D. redistribute the BGP routes into OSPF using the redistribute BGP 65001 subnet command. Answer: A Explanation: R2 is correctly configured for OSPF authentication, including the "ip ospf authentication message-digest" command listed properly under the sub-interface Serial0/0/0.12. R1 is missing this command.
