Hello all. I want to find out if it is feasible and possble to set up a backup connection to the Internet going through the T1 line between two offices and through the other ISP connection.
This is my Network diagram :
ISP1 --------Office 1 || || || || ISP2---------Office 2
---- : Fast Ethernet connection to ISP || : Frame Relay T1
I want to set it up so that if Office 1 loses Internet Connectivity the traffic can go through the T1 to the Office 2 and then out to the Internet.
I have Cisco 1721 and 3620 routers connecting the two offices. And Cisco PIX-515e's going to the Internet. I am running EIGRP on the T1.
I can try a load balancer like a Radware Link-Proof, but I am not sure that it will do the job.
Any suggestions are welcome.
Thank you in advance
Dmitry.
