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



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 not have routers connected.
·         R2 is configured with a default route pointing to the ISP and redistributes the default route.
·         NAT is configured on R2 and no untranslated addresses are permitted to cross the Internet.
WAN Technologies

·         The serial link between R1 and R2 uses Frame Relay.
·         The serial link between R2 and R3 uses HDLC encapsulation.
·         The serial link between R1 and R3 uses PPP with PAP.
Connectivity

·         Devices should be configured according to the Addressing Table.
·         Every device should be able to ping every other device.


Troubleshooting Documentation



Verification Documentation

Capture output from verification commands and provide documentation proving that each of the requirements has been satisfied.

Suggested Scoring Rubric

Packet Tracer scores 60 points. The troubleshooting documentation and instructor verification is worth 40 points.

[CCNAv6 S2] 2.2.2.4 Packet Tracer - Configuring IPv4 Static and Default Routes

Hình ảnh
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...
