[CCNAv6 S3] 9.2.2.6 Packet Tracer - Configuring Multiarea OSPFv2




Packet Tracer – Configuring Multiarea OSPFv2
Addressing Table


Background

In this activity, you will configure multiarea OSPFv2. The network is already connected and interfaces are configured with IPv4 addressing. Your job is to enable multiarea OSPFv2, verify connectivity, and examine the operation of multiarea OSPFv2.

Part 1:     Configure OSPFv2
Step 1:     Configure OSPFv2 on R1.

Configure OSPFv2 on R1 with a process ID of 1 and a router ID of 1.1.1.1.

Step 2:     Advertise each directly connected network in OSPFv2 on R1.

Configure each network in OSPFv2 assigning areas according to the Addressing Table.

R1(config-router)# network 10.1.1.0 0.0.0.255 area 1
R1(config-router)# network 10.1.2.0 0.0.0.255 area 1
R1(config-router)# network 192.168.10.0 0.0.0.3 area 0
Step 3:     Configure OSPFv2 on R2 and R3.

Repeat the steps above for R2 and R3 using a router ID of 2.2.2.2 and 3.3.3.3, respectively.

Part 2:     Verify and Examine Multiarea OSPFv2
Step 1:     Verify connectivity to each of the OSPFv2 areas.

From R1, ping each of the following remote devices in area 0 and area 2: 192.168.1.2, 192.168.2.2, and 10.2.1.2.

Step 2:     Use show commands to examine the current OSPFv2 operations.

Use the following commands to gather information about your OSPFv2 multiarea implementation.

show ip protocols
show ip route
show ip ospf database
show ip ospf interface
show ip ospf neighbor

[CCNAv6 S4] 8.2.4.14 Packet Tracer - Troubleshooting Enterprise Networks 3

Hình ảnh
Packet Tracer – Troubleshooting Enterprise Networks 3 Addressing Table Background This activity uses a variety of technologies you have encountered during your CCNA studies, including routing, port security, EtherChannel, DHCP, NAT, PPP, and Frame Relay. Your task is to review the requirements, isolate and resolve any issues, and then document the steps you took to verify the requirements. Note: This activity begins with a partial score. Requirements DHCP ·         R1 is the DHCP server for the R1 LAN. Switching Technologies ·         Port security is configured to only allow PC1 to access S1's F0/3 interface. All violations should disable the interface. ·         Link aggregation using EtherChannel is configured on S2, S3, and S4. Routing ·         All routers are configured with OSPF process ID 1 and no routing updates should be sent across interfaces that do n...

Packet Tracer - Configuring IPv4 Static and Default Routes Addressing Table Objectives Part 1: Examine the Network and Evaluate the Need for Static Routing Part 2: Configure Static and Default Routes Part 3: Verify Connectivity Background In this activity, you will configure static and default routes. A static route is a route that is entered manually by the network administrator to create a reliable and safe route. There are four different static routes that are used in this activity: a recursive static route, a directly attached static route, a fully specified static route, and a default route. Part 1:     Examine the Network and Evaluate the Need for Static Routing a.     Looking at the topology diagram, how many networks are there in total? b.    How many networks are directly connected to R1, R2, and R3? c.     How many static routes are required by each router to reach networks that are not directly ...

Packet Tracer – Skills Integration Challenge Addressing Table VLAN Port Assignments and DHCP Information Scenario In this culminating activity, you will configure VLANs, trunks, DHCP Server, DHCP relay agents, and configure a router as a DHCP client. Requirements Using the information in the tables above, implement the following requirements: ·         Create VLANs on S2 and assign VLANs to appropriate ports. Names are case-sensitive ·         Configure S2 ports for trunking. ·         Configure all non-trunk ports on S2 as access ports. ·         Configure R1 to route between VLANs. Subinterface names should match the VLAN number. ·         Configure R1 to act as a DHCP server for the VLANs attached to S2. -       Create a DHCP pool for each VLAN. Names are case-sensitive. -       Assign the ap...
