Automatic switching of route in Cisco 3750 Switch

[kjanakiraman]

Hi,

I have Cisco 3750 Switch which is connected to a Cisco Pix Firewall and to internet router. Now i have one more T1 line from different ISP and i do have one more Cisco Pix firwall. What i want is if one firewall or the router goes down then the traffic should automatically go through the other firewall and the router. Can we have the option for this in the switch? I tried with the default routing statement but the automatic switching did not work.

Can someone advice me how to proceed.

Thanks in Advance

If your network is like this :

-> Pix -> router

3750swx

-> Pix -> router

then you can configure your 3750 switch which supports HSRP .Hot Standby Routing Protocol (HSRP) provides dynamic load balancing and failover for routed links, up to 32 HSRP links supported per unit or stack.

interface ethernet fa0/2

ip address 1.0.0.1 255.0.0.0

standby 1 ip 1.0.0.2

standby 1 preempt

standby 1 priority 110

standby 1 authentication denmark

standby 1 timers 5 15

Guess this should work
