Comment:

This configuration describe that VLAN1 also configured with the virtual router (HSRP)

The original lab: vritual router (HSRP) only for VLAN11 and VLAN12

Task 1: Configure HSRP on the Router

Step 1:

Identify the table

Step 2: & Step 3:

DSW1>enable

DSW1#conf t

DSW1(config)#

for VLAN11 primary router is DSW1

for VLAN12 primary router is DSW2

Step 4: Step 5: Step6:

interface Vlan11

ip address 10.1.11.1 255.255.255.0

standby 1 ip 10.1.11.254

standby 1 priority 150

end

interface Vlan12

ip address 10.1.12.1 255.255.255.0

standby 2 ip 10.1.12.254

standby 2 timers msec 200 msec 700

end

Step 7:

DSW1#sh standby brief

P indicates configured to preempt.

Interface Grp Prio P State Active Standby Virtual IP

Vl1 1 80 Standby 10.1.1.2 local 10.1.1.250

Vl11 2 150 P Active local 10.1.11.2 10.1.11.254

Vl12 3 100 Standby 10.1.12.2 local 10.1.12.254

DSW1#

Step 8: Answer this questions:

Which active router? Which Standby router? What is the priority of them? Is the router with the highest priority active? Why or Why not?

Task 2: Test HSRP on Router by Simulating a Failure

Step 1 – Step 8: Only testing and running the scenarios

Task 3: Test HSRP Tuning Enhancements Using Preempt

Step 1:

DSW1(config)#interface vlan 11

DSW1(config-if)#standby 1 preempt

DSW1(config)#interface vlan 12

DSW1(config-if)#standby 2 preempt

Step 2 - Step 7: Only testing and running the scenarios

Step 8: Answer the questions

Task 4: Troubleshoot HSRP on the Routers

Extra Task: Display Configurations

note:

preempt --> using only for forcing the “chosen active router” by the priority number
