Load Balance in router ethernet interfaces

[fred_m]

Hi guys,

I have a cisco 2800 with 2 ethernets.

How can i configure same ip on both, plug one in my first switch and second ethernet in second switch and both do a load balance and fail over ?

Thanks.

implement HSRP that is the best solutions to load balance.

Anand,

You can not implement HSRP on a single router interfaces. Original poster is looking for load-balancing between the same router's ports.

Please see my post below for this :

HTH,Please rate if it does.

Amit,

Your tip is not my case.

Let me explain better.

I have two switches cisco and all of my servers have two NIC's. I plug each NIC on differnt switch, but i need do a trunk link between because i have only one inteface to my route.

So i want plug eth0 router interface in switch A and eth1 in switch B and remove this trunk.

Both eth0 and eth1 have same ip address.

If one of switches stop to work my network isn't impacted.

Thanks.

Hi Fred,

Amit's suggestion is almost your only chance, as you can't have 2 Ethernet interfaces with the same IP subnet on a single router.

HTH, please do rate all helpful replies,

Mohammed,

I thinked that exist some way like HSRVP to solve this question.

Thanks.

Fred,

No, you can not implement HSRP on a single router, and further more you can't use the same IP (or even 2 IPs from the same IP subnet) on 2 different interfaces on the same router, and thus Amit's suggestion is almost your only choice.
