Question : Problem: Configuring a failover cluster on two Cat3560G switches

I need to configure a failover cluster with two Cat3560G switches, and one of the switches is already live on the network. A friend of mine told me that it can be done with HSRP (Hot Standby Routing Protocol). I was wondering exactly how I would do this.

Answer : Problem: Configuring a failover cluster on two Cat3560G switches

with HSRP, you pick an interface to monitor and then if that interface 'goes down' traffic will be routed to the standby router.  So say you want to monitor interface ethernet0/0:

Configuring HSRP is easy. All we configure is

interface ethernet 0
ip address 131.108.1.1 255.255.255.0
standby 2 ip 131.108.1.3

On the second router attached to the Ethernet LAN:

interface ethernet 0
ip address 131.108.1.2 255.255.255.0
standby 2 ip 131.108.1.3
