*Task 1*
Configure VLAN25 such that half of the users use R2 as the primary default
gateway and R5 as the backup. The other half should use R5 as the primary
and R2 as their backup default gateway. Use the following IP addresses to
accomplish this task:
131.1.25.22 /24 and 131.1.25.55 /24
* *
*On R2*
* *
R2(config)#int f0/0
*R2(config-if)#standby 1 priority 200*
*R2(config-if)#standby 1 preempt*
*R2(config-if)#standby 1 ip 131.1.25.22*
R2(config-if)#standby 2 ip 131.1.25.55
*On R5*
R5(config)#int f0/0
R5(config-if)#standby 1 ip 131.1.25.22
*R5(config-if)#standby 2 ip 131.1.25.55*
*R5(config-if)#standby 2 preempt*
*R5(config-if)#standby 2 priority 200*
* *
* *
*To verify the configuration:*
* *
*On R2*
* *
*show standby brief*
* *
P indicates configured to preempt.
