Trong bài lab này, chỉ cần thực hiện cho R6 và R7 Các routers khác không cần quan tâm Các tác vụ yêu cầu như sau:

Xin được giữ nguyên bản tiếng Anh (source IPExpert)

1) Enable HSRP support on R6 and R7 A virtual IP address of 150.50.7.10 should be used The virtual mac-address should be 0001.0023.0456

2) Ensure that R6 is the active HSRP router, If R6 fails, part of HSRP, R7 should take over as the active HSRP router When R6 comes back and is available to be the active router again, it should take this responsibility over from R7 after 60 seconds

3) R6 and R7 should exchange hello packets every 20 seconds and they should wait for

60 seconds before declaring a router down

4) If the serial interface on R6 goes down, R7 should become the active router Don't change the router priority on R7

5) Configure R6 and R7 to use authentication string of packattack for HSRP

authentication

6) Configure HSRP support on the Ethernet interface of R5, R6, and R7 with a virtual IP address of 150.50.64.10 R5, R6, and R7 can use IP addresses on their Ethernet interfaces

of 150.50.64 with a mask of /24, but this should not replace the current IP addressing on the 150.50.7.0/25 network The existing HSRP group that was configured in steps 1-5 should be maintained Do not use VLANs

7) Ensure that R6 will only be the active router if both R5 and R7 fail R5 should be the active router in normal network operations

8) If R5 were to fail and R7 became the active router, when R5 came back up it should immediately become the active router again

Khi dùng HSRP, có thể có nhiều nhóm trên cùng một interface Hãy dùng lệnh show standby để xem các thông số của protocol HSRP Độ ưu tiên mặc định của HSRP là 100 Router có độ ưu tiên cao hơn sẽ chiếm vai trò active
