Dear Professionals

With all due respect, Sir my concern is i want to know how to setup two different locations office with a backup internet connection and connect them together to share the resources and when one connection goes down then second connection automatically connect the sites without any interruption. A bit more detail is given below
 
Site 1 (1 router, 1 switch, 2 internet connections from two different isp)
 
Site 2 (1 router, 1 switch, 2 internet connections from two different isp)
 
I want to configure mpls and internet access line both seperately on a single switch on different ports and my concern is if one internet goes down then instead of the whole mpls for local network goes down the second internet line keeps the connectivity on. 
 
Please help me i really need to learn this.
for more detail i have attached a picture for understanding.

Re: Dear Professionals

Hello,

 

here is the thing: Packet Tracer is a simulator with only a limited set of commands. On 'real' routers, you could use IP SLAs to achieve failover. That would look like below. If the main default route is down, the secondary default route would kick in. Unfortunately, Packet Tracer does not support that. Your other option would be to use a routing protocol such as BGP, and manipulate the metric. In BGP, you could use the weight attribute to prefer one path over the other.

Re: Dear Professionals

Hello,

 

typically, you would achieve this with IP SLAs or configuring one of the interfaces with the 'backup interface' command. Or you can run a dynamic routing protocol and manipulate the metrics. If possible, post the Packet Tracer project file (.pkt), zip it first, otherwise the system won't let you upload it. Keep in mind that Packet Tracer has only a limited set of commands, and 'real' IOS routers have much more extensive options...
