Interface E0/0/20 on SW1 is directly connected to a PC. Ensure that E0/0/20 enters the forwarding state as soon as the PC is connected and the link becomes active. E0/0/20 should to be shut down automatically after receiving BPDUs and should recover after 50s.
Frame Relay
R1, R2 and R3 use Frame Relay (FR) encapsulation and are connected in “hub and spoke” mode with R2 as the hub. S1/0/0.2 on R2 and S1/0/0.1 on R3 may not use static mapping, inverse ARP must be disabled on all devices.
R1, R4 and R5 use Frame Relay (FR) encapsulation and are connected in “hub and spoke” mode with R1 as the hub. Inverse ARP must be disabled on all devices and sub-interfaces may not be used.
R1 connects to R4 using DLCI 104 and R5 using DLCI 105, R4 connects to R1 using DLCI 401 and R5 connects to R1 using DLCI 501. Only the specified DLCIs may be used. All these FR interfaces should be able to ping each other.
Perform the following configuration to ensure that R2 can communicate with R1 and R3: Configure R1 to connect to R2 using DLCI 102. Configure R2 to connect to R3 using DLCI 203. Configure R2 to connect to R1 using DLCI 201. Configure R3 to connect to R2 using DLCI 302.

Section 2: IGP 2.1
Basic Configurations
When implementing IP addressing, replace Y with your rack number and replace X with the device number. For example the device numbers of R1, R2, SW1 and SW2 are 1, 2, 11 and 22. The IP addresses on all physical interfaces use 24-bit masks. All routers have Loopback0 interfaces with an IP address of 10.Y.X.X and a 24-bit mask.
Configure IP addresses on device interfaces as per the information in the IPv4 logical topology diagram. SW1 VLAN interfaces 3, 62 and 41 should be assigned IP addresses 10.Y.33.11/24, 10.Y.62.11/24 and 10.Y.41.11/24, respectively. SW2 VLAN interfaces 62 and 18 should be assigned IP addresses 10.Y.62.22/24 and 10.Y.32.22/24, respectively.
The IP address of the interface that connects R6 to BB1 is 157.68.1.6/24. The IP address of the interface that connects R6 to BB2 is 157.68.2.6/24. The IP address of the interface that connects R4 to BB3 is 157.68.3.4/24.

Set the IP address of VLANIF 41 as the router ID of SW1.
Basic IS-IS
IS-IS runs on the connected interfaces between R1, R2 and R3 as well as their loopback interfaces. IS-IS also runs on the interfaces between R6 and R2, the loopback interface of R6 and VLANIF 18 on SW2. All devices belong to area 49.0001 and all routers are Level 1 routers. Set the system ID to 0000.0000.000X and the IS-IS process ID to Y.
On R6, import BB2 network segment 157.68.2.0/24 into IS-IS and set the cost of imported routes to 200 and tag to 200.
2.3
IS-IS Optimization
Where equal-cost routes exist on R1 and R3, the route over FR network should be preferred. The standby command may not be used.
When IS-IS neighbor relationships change state, the change should be logged.
Establish a reliable neighbor relationship without DIS between R2 and R6.
2.4
2.5
IS-IS Verification Hello packets sent from FR interfaces on R1, R2 and R3 should be authenticated. Use a password of HuaWei, which should be transmitted in plain text and be displayed in plain text in the display current-configuration command output.
Base OSPF
All OSPF routers should use a process ID Y.
Advertise network segments where both Loopback 0 on R4 and R5 and E2/0/0 on R5 reside into Area 0.
OSPF should run in area 0 on the FR links between R1, R4 and R5. The network command may not be used within the OSPF process configuration of R1. Change the network type of Area 0 to broadcast, and ensure that R1, R4, and R5 can learn routes from each other after restarting these devices or OSPF processes.Ensure the Loopback interface addresses of R4 and R5 are shown with the full 24bit mask in the OSPF routing tables.
2.6
OSPF Area Partition
Use the network command to add the PPP link between R4 and R5 to OSPF area 2.
Advertise network segments where both E2/0/0 on R4 and VLANIF41 on SW1 reside into Area 1.
Advertise network segments where VLANIF 62 on SW1 and SW2 resides into Area 3.

QoS Configuration
Configure SW2 to police received traffic with an 802.1p priority of 1, set the CIR to 1000 kbit/s. The police should allow green and yellow packets to pass through, re-mark the 802.1p priorities of green and yellow packets to 4 and 7 respectively, red packets should be discarded.
Configure inbound traffic policing on R3 S1/0/1 and set the CIR to 2000 kbit/s.
Set the DSCP priority of voice packets to EF. The voice packets are received by G0/0/2 on SW2 and contain source address 10.1.26.201 and destination address 10.1.33.201.
The three types of packets – NMS control, video, and data packets – received by R1 are marked with different DSCP priorities. The DSCP priorities are cs6, af21, and af11 respectively. NMS control, video, and data packets sent from R1 to R3 must occupy 5%, 30%, and 45% of bandwidth respectively. Configure congestion avoidance and set the following parameters. For data packets, set the upper drop threshold to 85, lower drop threshold to 70, and maximum drop probability to 6. For video packets, set the upper drop threshold to 95, lower drop threshold to 80, and maximum drop probability to 60.

Header Configuration When a user connects to R3, the message "Please do not attempt to log in to this system if you are not authorized!"should be displayed on the terminal.
Port Security SW1 E0/0/20 should accept a maximum of 2 secure dynamic MAC addresses. Any frames from MAC addresses which are not one of the secure dynamic entries on SW1 E0/0/20 should be discarded. A trap should be generated on SW1 when E0/0/20 learns more than two secure dynamic MAC address entries. If SW1 is restarted, the learned MAC addresses should not be lost.
uRPF
DoS attacks with forged source IP addresses occur on E2/0/1 of R3. To solve this problem, use URPF for IPV4 packets on E2/0/1 of R3.
Configure uRPF for IPv6 packets on R3 E2/0/1. Packets with a source addresses in the FIB may be forwarded. It is not necessary for the outbound interface in the FIB to match the inbound interface of the packets.
