Scenario 6 Router Redundancy with Hsrp Vrrp and GLBP

This scenario covers two methods by which you can configure multilayer switches to provide redundant router or gateway functionality: HSRP, VRRP, and GLBP.

A network consists of two VLANs: 101 and 102. Suppose that the PCs in VLAN 101

(192.168.101.0/24) use address 192.168.101.1 as their default gateway. The PCs in VLAN 102

1. What commands are necessary to configure HSRP on a Catalyst switch so that it becomes the active router for VLAN 101 and the standby router for VLAN 102? If a failed router interface is restored, control should be passed back to it from the HSRP standby router. (You can use IP addresses 192.168.101.2 and 192.168.102.2, if needed.)

2. What commands can you use to configure VRRP for the network described in question 1?

3. GLBP is to be used in the network shown in Figure 20-6. Answer the following questions about this network.

a. What command should you use to make Catalyst B become the active virtual gateway (AVG) for GLBP group 10?

b. The virtual gateway address is 192.168.10.1. Which switches should be configured for this, and with what command?

c. Give the command needed on the AVG to implement round-robin load balancing, evenly distributing the virtual gateway MAC addresses across the set of AVFs.

d. Each of the AVF switches must be configured to become members of GLBP group 10. How can this be accomplished?
