I just purchased a cisco 2921 ISR. I want to set it up to be inbetween our switches and our internet connections. I added an extra port to handle the extra connection (so a total of 4).
Our company is setup like this:
T1 - Main internet. (x.x.x.248)
Marketing DSL (x.x.x.251)
Media DSL. (x.x.x.254)
I want to put the isr inbetween the switches and these three wan or isp connections. The two dsl connections are for seperate use by other departments so they don't kill our bandwith. The setup would be to move the internet connectons from our switches to the router. Then have a network cable joining the router to our switches. Then I can do some routing on the traffic.
I don't wan to have to change the IP's of each of the gateways. How can I do this?
I don't want any load balancing, or failover. Just the x.x.x.248 as the route of last resort and have trafic go to the correct isp if they specify x.x.x.251 or x.x.x.254 as the gateway on their pc's.
Thanks in advance.
