Van Oene Lab Scenario Phase 1: Layer 1/2 Topology Phase 2: IP Addressing Phase 3: CLNS Addressing Phase 4: Basic ISIS Configuration Phase 5: ISIS Security Completion Criteria Solution Configurations R1 R2 R3 R4 R5 Routing Tables R1 R2 R3 R4 R5 Link State Databases R1 R2 R3 R4 R5 Adjacencies R1 R2 R3 R4 R5 Lab Scenario CertificationZone Page 2 of 12 http://www.certificationzone.com/studyguides /?Issue=35&IssueDate=04-01-2001&CP= 11/06/01 Phase 1: Layer 1/2 Topology 1. Physically cable the routers as depicted in the corresponding diagram. 2. The frame relay cloud between R1, R2, and R3 should be partially meshed with no PVC between R1 and R2. 3. The link from R4 to R5 should be 2 Mbps with R4 providing clocking. 4. Each router should have only the necessary physical interfaces turned up along with one loopback each. 5. R3's S0 must use sub interfaces. Phase 2: IP Addressing 1. Assign each router a loopback address from the 150.100.0.248/29 subnet. 2. Assign R3's S0 the address 150.100.0.1/29. 3. Assign R4's E0 the address 150.100.0.193/28. 4. Fill in the rest of the addresses appropriately from within the 150.100.0.0/24 prefix. Phase 3: CLNS Addressing 1. Use each router's Loopback address as the System ID. 2. Assign R1 the Area ID 47.0001. 3. Assign R2 an Area ID different from R1. 4. Assign R4 an Area ID different from R1 and R2. 5. Assign R5 the same Area ID as R4. Phase 4: Basic ISIS Configuration 1. All routers must be configured as Level 1 only. 2. R3's E0 must be the DR for the segment between itself and R4. 3. ISIS Hello packets should be sent every 30 seconds from R4's E0 interface. 4. Assign the metric 20 to R5's Serial 0. Phase 5: ISIS Security 1. An area password of CZarea should be configured on R3. 2. All adjacencies should be authenticated with the password Czadj. Completion Criteria 1. All interfaces must be able to reach all other interfaces.
