Configuring and Verifying HSRP v1.1 Introduction Hot Standby Router Protocol (HSRP) is a Cisco proprietary protocol that provides a redundant gateway for hosts on a local subnet. HSRP allows configuration of two, or more, routers into a standby group that share an IP address and MAC address, while also providing a default gateway. Objective(s) In this lab the student will: Configure and Verify HSRP Equipment/Supplies Needed Computer with Internet connection Cisco Packet Tracer Configuring and Verifying HSRP.PKA file Assignment Perform the steps in this lab in the order they are presented to you. Answer all questions and record the requested information in this lab file . Configure Lab Network 1. Configure the network as shown. If using Cisco Packet Tracer, recreate the topology as shown. If using Packet Tracer, the topology has already been created. ITNW 2312 Lab 5.1.2 Configuring and Verifying HSRP 1
2. Configure the router’s ( HSRP1, HSRP2 ) Ethernet interfaces as shown in the diagram. If your router does not have interfaces as depicted in diagram, change the lab as required to your router interfaces [ie. Serial 0/0 vs Serial 0/0/0 etc.] Annotate changes on your diagram to keep you on track. Remember, you can always type in show ip int brief from Privileged Mode to see the interface types.

3. The computers in this lab are just connection points. No configuration is necessary. 4. The following commands set the virtual router IP, standby group and sets the interface on router HSRP1 so that it wins the election and becomes the active router by default. HSRP1# config t HSRP1(config)# interface G0/0 HSRP1(config-if)# standby 1 ip 192.168.1.10 HSRP1(config-if)# standby 1 priority 110 5. The following commands set the virtual router IP and standby group on router HSRP2 . HSRP2# config t HSRP2(config)# interface G0/0 HSRP2(config-if)# standby 1 ip 192.168.1.10 6. Verify that HSRP took effect by using the following commands: HSRP1# show standby HSRP1# show standby brief Testing HSRP Operations 1. Ping from PC’s to the Internet: a. Ping from PC-A to the Internet (10.10.10.10). ITNW 2312 Lab 5.1.2 Configuring and Verifying HSRP 3 At the bottom of your packet tracer, you will see 3 PDU tests built. These tests will ping the items show below to test. You can use these PDU to view your connectivity results.

PC-A has a default gateway of R1 (192.168.1.2) b. Ping from PC-B to the Internet (10.10.10.10). PC-B has a default gateway of R2 (192.168.1.3) c. Ping from “PC-Using HSRP” to the Internet. This PC’s default gateway is set to the HSRP virtual IP of 192.168.1.10, protecting the default gateway. 2. Now go int R1 and power it down. a. Record the above ping results again. (PC-B and PC HSRP both pass but PC-A did not) b. Power R1 back up and wait for results to be normal. 3. Now go to R2 and power it down. a. Record the above ping results again. (PC-A passed but took a few minutes. HSRP and PC-B did not) b. Power R2 back up and wait for results to be normal. Summary: PC-A and PC-B are vulnerable to router outages, however the PC using HSRP as it’s gateway might see a short outage, but should recover. Please summarize your observations. HSRP did recover but 1 side seemed to only work when the opposite side was shut off. What would happen if all the PC’s were set to the new default gateway offered in DHCP? I feel like if the PCs were set to the new default gateway, it could cause issues if there were network issues (shut off router) but it would also serve as a faster way to deliver packets to the PCs. If completing this lab online , save the Packet Tracer file as 5.1.2 Configuring and Verifying HSRP as well as this Lab document with your answers embedding. If completing this lab in class , save your show standby, show standby brief and show run commands in a document titled 5.1.2 Configuring and Verifying HSRP.
