1 QUESTION/SOLUTION SET LAB 4

2 CCIE lab Routing & Switching (v4.0) lab:4 Updated

3 Testing Guidelines 1. The equipment on the rack assigned to you is physically Cabled and should not be tempered with. 2. Router and Switch hostnames, basic ip addressing, no exec-timeout and passwords on the Con, AUX and VTYs have been preconfigured. Do not change these configurations. 3. All preconfigured passwords are cisco.do not change these passwords. 4. Static and default routes are not permitted unless directly stated in a question. This includes floating static routes. 5. Routers to Null generated as a result of a dynamic routing protocol solution are permitted. 6. If you need clarification on the meaning of a question, or, if you suspect hardware problems with you equipment, contact the lab proctor as soon as possible. 7. The following symbols are used throughout the exam: YY is your 2-digit rack number, for example YY value for Rack3 is 03 and for Rack11 is 11. X is your router number, for example X Value for router 1 is 1. Z is any number SW1 and SW2 refer to the Catalyst

46 SECTION I. Layer 2 Technologies 1.1 Troubleshoot Layer 2 Switching A few faults have been injected into the pre-configurations just described, These issues may impede a working solution for certain portions of this labs exam and affect any labs exam section. You must verify that all of your configurations work as expected, if something is not working as expected then you must fix the underlying problem. Point will be awarded for solving each problem. However, if you fail to solve a particular problem, and the injected fault prevents you from having a working solutions of this lab, then you will lose points for the fault and the scenario that is not working Score : Solve one fault 2point, solve two fault 4point FAULT 1

48 1.2 Implement the Access-Switch Ports of Switched Network Configure all of the appropriate spanning-tree domains on Sw1, Sw2, Sw3 and Sw4, according to the following requirements :- SW1 is the server for the VLAN Trunking Protocol(VTP) version 2 domain CCIERoutingandSwitching +YY (for example, the rack number of 3 would have a VTP domain of Q trunks between all switches) VTP password cisco both without quote. PPP on the serial links between R1 and R4, R2 and R4. Sw2, Sw3 and SW4 are expecting Sw1 to update their VLAN database when needed. Configure the VLAN ID and Name according to the table below (case sensitive) Configure the Access ports for each VLAN as per the diagram. Using a single command ensure that all access ports are transitioned to forwarding state as quickly as possible. Using a single command ensure that the interface is forced the err-disabled state if a BPDU is received by any access ports. Ensure that any BPDU received by the access ports facing the backbone devices ( and only these ports) have no effect to your spanning-tree decision Don t forget to configure the Layer 3 interfaces and to include SW1 s port fa0/4 into VLAN 44

66 1.3 Implement Spanning Tree ( STP ) Configure the spanning-trees on Sw1, Sw2, Sw3 and Sw4 according to the following requirements :- Configure VLANs for Backbones should be in instance 1 and VLANs throughout your network should be in instance 2. All other VLAN should be in default spanning-tree instance. Ensure that Sw1 must be the root for instance 1 with Sw2 being the backup for instance 1.

70 1.4 Implement the Additional Spanning-Tree Configure the additional spanning-trees Switches according to the following requirements : Configure Spanning-tree timers such that if no BPDU was received within 30 seconds, that the network re-converges. Ensure port Fa0/20 is forwarding rather than blocking for MST 1 on SW3. Ensure port Fa0/20 is forwarding rather than blocking for MST 2 on SW4. You must do this without any configuration on SW3 and SW4. Use the highest numerical value to accomplish this task. Or Use the lowest numerical value to accomplish this task.(in that case on SW1 int fa0/20 make spanning-tree mst 1 port priority 0 and on SW2 int fa0/20 make spanningtree mst 2 port priority 0 Score : 2 Point

85 SECTION ll. Layer 3 Technologies After finishing each of the following questions, make sure that all configured interfaces and subnets are consistently visible on all pertinent routers and switches Do not redistribute between any interior gateway protocol(igp) and Board Gateway Protocol(BGP) You need to ping a BGP route only if it is stated in a question, otherwise the route should be only in the BGP table. At the end of section 2, all subnets in your topology, including the loopback interfaces, must be reachable via ping. Therefore, redistribute as you wish unless directly stated in a question. The backbone interface must be reachable only if they are part of the solution to a question The loopback interface can be seen as either /24 or /32 in the routing tables unless stated otherwise in a question The loopback interfaces can be added into your IGP either via redistribution or added to a routing process of your choice

86 2.1 Implement IPv4 OSPF Configure Open Shortest Path First(OSPF) Updates should be advertised only out of the interfaces that are indicated in the IGP topology diagram. OSPF process ID is your Rack number, YY. Configure OSPF router ID with interface loopback 0 on respective router. Configure Area 0 between the Ethernet segments shared by all switches. Ensure SW1 should be control all routing, and SW2 should be the backup. Use the largest value to accomplish this task. Configure OSPF Area 142 between Sw1, R1, R4, R2 and Sw4. Configure OSPF Area 51 between Sw2, R5 and R3. Do not create any additional OSPF areas, unless required in the questions. All backbone networks should be seen as external type 2 on R4.

On R1 interface Loopback0 ip pim sparse-mode ip pim rp-candidate Loopback0 priority 0 On R2 interface Loopback0 ip pim sparse-mode ip pim rp-candidate Loopback0 priority 255 On R4 interface Loopback0 ip pim sparse-mode Use a non-proprietary dynamic method of learning the RP. ip pim bsr-candidate lo0 There is multicast source on VLAN_44 and clients are located on the BB3 subnet (150.3.YY.0 /24) On SW2 interface vlan 33 ip igmp join-group 239.YY.YY.1 Simulate that clients have sent requests to join the multicast group 239.YY.YY.1 and ensure they reply to pings from R4's f0/0

140 Verification

141 3.2 PIM Tuning Ensure that all multicast PIM register request are always sent upstream to the RP via SW1 It SW1 fails, another switch on VLAN 123 should be able to forward the PIM register requests upstream to the RP. Score : 3 Point

142 On SW1 interface vlan 123 ip pim dr-priority On SW4 Interface vlan 123 Ip pim dr-priority VERIFICATION

143 SECTION IV. Advanced Services 4.1 Network Address Translation (NAT) You are required to configure NAT in this task. The output must be matched with it provided the below. You are allowed to add only 1 static route on a maximum of 4 devices to accomplish this task. But do not use static on R4 Score : 3 Point NAT should be implemented on R4, with nat translations showing SW1 is pinging SW4 SW1 can be established SW4 with a new source not yet created on the SW. Thus create new loopback and ping SW4 with ip YY.YY.200.4

144 SW4 pinging SW1 with a new source also as per above, but pinging SW1 with ip YY.YY.100.1
