Hi Ciscoml320<br />
<br />
I am sorry for asking you this query after a long time...<br />
But can you pls tell me in your proposed diagram<br />
<br />
1..If I can load balance between (using route maps) the two ISP<br />
2..Will any link failure , apart from device failure also not cause any disruptions..<br />
3.. I have cisco L3 switches as well , how do i use it in your diagram.<br />
<br />
Pls reply and thanks in advance<br />

The two L3 switches are stacked using stacking cable , Also Please detail me the configuration between firewall and router also

<br />
We have one ISP , one router and one Firewall .<br />
We are going to buy another ISP , Router , Firewall .<br />
Can somebody tell how to create a redundancy <br />
<br />
1.One ISP fails internet should go thru the other , <br />
2.One router fails the other will take over<br />
3..One Firewall fails other will take over<br />
<br />
Can some body give me some links or explain the network arc in brief so that I can work on it.<br />

How to create redundancy in network

Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.

Hardware Firewalls

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.
