Failover or load balancing Question

[grahamhardy]

I am new to Cisco routers and would like some help to connect 2 internet connections to our LAN and provide load balancing or failover (prefered).

The 2 internet connections are provided by different ISP's. I have 1 Cisco 2600 router from ISP1 and a 1700 router from ISP2. The 2600 has a spare ethernet port and I was wondering if i can use this to connect to ISP2. Also could i just set the port to use a higher cost route so it only kicks in when ISP1 is down?

Any help will be gratefully received

Hi G,

well, you have n.2 gateways for your LAN. Normally we use HSRP for gateway redundancy.

Then, wich type of connection do you have for WAN services? Procotols eventually?

Thanks

Hi Andrea,

Thanks for the response. A couple of things here. What are n.2 gateways? and how do i configure HSRP? Also would our existing equipment support it?

We have a T1 connection and an sdsl connection.

Cheers

Graham

you just check it out which ios is on your router you should have any one IOS for HSRP on your 1700 series router:

12.3(14)T7 12.3(8)XX1 12.3(8)T9 12.3(7)XR6 12.3(7)T9 12.3(4)XQ1 12.3(4)XK4

12.3(4)XG5 12.3(4)T9 12.3(2)XF 12.3(2)XE1 12.3(2)XC2 12.3(2)XA1 12.3(2)T9 12.2(15)ZL

12.2(15)T9 12.2(13)ZH2 12.2(13)ZF2 12.2(13)T9 12.2(11)YV 12.2(11)YU 12.2(11)T9 12.2(8)YN

12.2(8)T8

you can check out your ios version using "show version" command...
