Hi Experts,
I want to configure simple Redundancy/Failover between these two sites only for internet access and each site have 1 mbps internet link of different ISP.
The distance between site A to site B is approximately 1 kms. Currently Both sites running Seperatly, there is no point to point connectivity but i drawn
in my attached network Diagram bcoz i will buy 2 mbps point to point LL with one Fastethernet HWIC card for each Router.
Plz see whole Network configuration below, i m not sure about that it is correct or not so make changes according to yourself.
Overall i need only two things with solution.
1. In my current setup, suppose isp1 goes down, that time Site A user can not access internet. suppose isp2 goes down,
that time Site B user can not access internet.
our requirement is, if isp1 goes to down, all internet traffic should go through isp2, if isp2 goes to down, all internet traffic should go through isp1.
then isp1 get back to normal, the internet traffic should back to isp1. is there any need to configure "Administrative Distance" ?
2. Site-A's LAN should be communicate with Site-B's LAN and Site-B's LAN should be communicate with Site-A's LAN
Things to be remember :
-- Once see my attached network Diagram
-- I am using only default Routing at Both Sites
-- No any Routing protocol here and also do not want to configure any Routing protocols
-- Plz do not use words like Load Balancing/ Load Sharing, only simple setup with static route and AD if requird
