1 CCNA3 Skills-based Assessment Part 1 of 2 Assessment of Intermediate Routing skills Objectives Preconfigs Configure OSPF with authentication Configure EIGRP Configure default routing and propagate it using OSPF Verify network connectivity Note: The command is added to FastEthernet0/0 interface. This will bring the interface up without having to connect a switch or a hub. The following items have been pre-configured on these devices: The topology cabling Hostname on all routers Interface IP address on the routers Interface clock rate on the routers 1 of 5 CCNA 3: Intermediate Routing Skills-based Assessment

2 Following are the actual commands already configured on the devices: Router1 hostname Router1 ip address interface Serial0/0 ip address clockrate Router2 hostname Router2 ip address interface Serial0/0 ip address interface serial0/1 ip address clockrate Router3 hostname Router3 ip address interface serial0/1 ip address of 5 CCNA 3: Intermediate Routing Skills-based Assessment

3 Configuration Tasks Configure OSPF with Authentication Configure OSPF routing between Router1 and Router2 with the process ID of 50. Configure OSPF so only the following subnets will be routed. o /27 o /30 Configure Router1 with the OSPF router ID of Configure Router2 with the OSPF router ID of Configure the OSPF hello interval to 5 seconds and the OSPF dead interval to 20 seconds. Configure the OSPF communication between the routers to use authentication with MD5 encryption. Configure EIGRP Configure EIGRP between Router2 and Router3 with an AS of 100. EIGRP should only route for the following networks. o /30 o /24 o /24 Configure Default Routing and propagate it using OSPF On Router 2, configure a default static route to Router 3. Propagate that default route to all routers in the OSPF routing domain. Verify connectivity Router2 should be able to ping all interfaces on all routers. Router1 and Router3 will not be able to ping all interfaces since there is no redistribution between OSPF and EIGRP in this scenario. Router1 should be able to ping all OSPF-enabled interfaces and Router3 should be able to ping all EIGRP-enabled interfaces. 3 of 5 CCNA 3: Intermediate Routing Skills-based Assessment

5 Configure EIGRP Configure EIGRP between Router2 and Router3 with an AS of 100. router(config)#router eigrp autonomous-system-number router(config-router)#network network-number EIGRP should only route for the following networks. o /30 o /24 o /24 Configure Default Routing and propagate it using OSPF On Router 2, configure a default static route to Router 3. Propagate that default route to all routers in the OSPF routing domain. ip route (config-router)# default-information originate Verify connectivity Router2 should be able to ping all interfaces on all routers. Router1 and Router3 will not be able to ping all interfaces since there is no redistribution between OSPF and EIGRP in this scenario. Router1 should be able to ping all OSPF-enabled interfaces and Router3 should be able to ping all EIGRP-enabled interfaces. 5 of 5 CCNA 3: Intermediate Routing Skills-based Assessment
