EIGRP OSPF Redist Sim You are a network engineer with ROUTE.com, a small IT company. They have recently merged two organizations and now need to merge their networks as shown in the topology exhibit. One network is using OSPF as its IGP and the other is using EIGRP as its IGP. R4 has been added to the existing OSPF network to provide the interconnect between the OSPF and EIGRP networks. Two links have been added that will provide redundancy. The network requirements state that you must be able to ping and telnet from loopback 101 on R1 to the OPSF domain test address of 172.16.1.100. All traffic must use the shortest path that provides the greatest bandwidth. The redundant paths from the OSPF network to the EIGRP network must be available in case of a link failure. No static or default routing is allowed in either network. A previous network engineer has started the merger implementation and has successfully assigned and verified all IP addressing and basic IGP routing. You have been tasked with completing the implementation and ensuring that the network requirements are met. You may not remove or change any of the configuration commands currently on any of the routers. You may add new commands or change default values.

Policy Based Routing Sim Company Acan has two links which can take it to the Internet. The company policy demands that you use web traffic to be forwarded only to Frame Relay link if available and other traffic can go through any links. No static or default routing is allowed.

IPv6 OSPF Virtual Link Sim Acme is a small export company that has an existing enterprise network that is running IPv6 OSPFv3. Currently OSPF is configured on all routers. However, R4‘s loopback address (FEC0:4:4) cannot be seen in R1‘s IPv6 routing table. You are tasked with identifying the cause of this fault and implementing the needed corrective actions that uses OSPF features and does no change the current area assignments. You will know that you have corrected the fault when R4‘s loopback address (FEC0:4:4) can be seen in the routing table of R1.
Special Note: To gain the maximum number of points you must remove all incorrect or unneeded configuration statements related to this issue. 1. on all 4 routers: show running-config - see that R2 and R3 do not have a virtual link set up - this is needed as Area54 needs a virtual link to connect to Area 0 - R4 does have a virtual link that needs to be removed. 2. set up virtual link between R2 and R3 ``` on R2 enable configure terminal ipv6 router ospf 1 area 11 virtual-link 3.3.3.3 ``` ``` on R3 enable configure terminal ipv6 router ospf 1 no area 54 virtual-link 4.4.4.4 area 11 virtual-link 2.2.2.2 ``` ``` 3. remove the virtual link from R4 on R4 enable config terminal ipv6 router ospf 1 no area 54 virtual-link 3.3.3.3 ``` 4. Ping from R4 to R1 5. Confirm R4's loopback can be seen in R1's routing table on R1 show ipv6 route 6. IF THE ROUTE TO R4 IS NOT IN R1'S ROUTING TABLE, advertise the IPv6 Loopbacks into OSPFv3 first on R4 int loopback 0 ipv6 ospf 1 area 54 on R1 int loopback 0 ipv6 ospf 1 area 0

EIGRP Stub Sim By increasing the first distant office, JS manufactures has extended their business. They configured the remote office router (R3) from which they can reach all Corporate subnets. In order to raise network stableness and lower the memory usage and broadband utilization to R3, JS manufactures makes use of route summarization together with the EIGRP Stub Routing feature. Another network engineer is responsible for the implementing of this solution. However, in the process of configuring EIGRP stub routing connectivity with the remote network devices off of R3 has been missing. Presently JS has configured EIGRP on all routers in the network R2, R3, and R4. Your duty is to find and solve the connectivity failure problem with the remote office router R3. You should then configure route summarization only to the distant office router R3 to complete the task after the problem has been solved. The success of pings from R4 to the R3 LAN interface proves that the fault has been corrected and the R3 IP routing table only contains two 10.0.0.0 subnets.
1: on R3 - find out why R3 and R4 cannot talk show running config router eigrp 123 eigrp stub receive-only (receive-only means it won't share routes in this AS) ``` 2: remove receive-only configure terminal router eigrp 123 no eigrp stub receive-only eigrp stub end (now AS will share - connected and summary are shared by default) ``` 3: configure R3 so it has only 2 subnets in 10.0.0.0 show ip route (to see how many routes it has) 4: on R4 port s0/0 connected to R3, set the subnets to summary enable configure terminal interface s0/0 !if you don't see 10.0.0.0/8 is a summary ip summary-address eigrp 123 10.2.0.0 255.255.0.0 !if you do see 10.0.0.0/8 is a summary ip summary-address eigrp 123 10.0.0.0 255.0.0.0 5 on R3, see if the summary was successful show ip route copy running-config startup-config ping to test

OSPF Sim OSPF is configured on routers Amani and Lynaic. Amani‘s S0/0 interface and Lynaic‘s S0/1 interface are in Area 0. Lynaic‘s Loopback0 interface is in Area 2. Your task is to configure the following: Portland’s S0/0 interface in Area 1 Amani’s S0/1 interface in Area 1 Use the appropriate mask such that ONLY Portland’s S0/0 and Amnani’s S0/1 could be in Area 1. Area 1 should not receive any external or inter-area routes (except the default route).
1. determine the IPs on Portland s0/0 and Amani s0/1 to create a network command that only includes these 2 IPs and puts them in Area 1 ``` IPs: 192.168.4.5/30 and 191.68.4.6/30 - /30 has 4 IPs (192.168.4.4, 4.5, 4.6 and 4.7) - changing /30 to a wlidcard is 0.0.0.3 - so the command will be: network 192.168.4.4 0.0.0.3 area 1 ``` On Amani, put s0/1 in Area 1 ``` on Portland configure terminal router ospf 1 network 192.168.4.4 0.0.0.3 area 1 area 1 stub end copy running-config startup-config ``` ``` on Amani configure terminal router ospf 1 network 192.168.4.4 0.0.0.3 area1 area 1 stub no-summary end copy running-config startup-config ```
