We have a 512 kbps link Internet connection from an ISP say ISP1. We are connected to the Internet through a DLINK DI-804HV router and a DLINK DFL-300 Firewall. Now we want to enhance our speed from 512 kbps to 1 Mbps. But instead of enhancing the same link, we are planning to get another 512 kbps link from another ISP say ISP2 so that both will be redundant to each other.
As the existing Router and Firewall each have single WAN port, we are planning to upgrade to Cisco Devices with at least two WAN ports each.
Suppose, in our Cisco router, S0 port connects ISP1 with Default Gateway address 22.214.171.124 255.255.255.0 and S1 port connects ISP2 with Default Gateway address 126.96.36.199 255.255.255.0. My ethernet side address is 192.168.1.x and connected to a switch.
I write two static routes (default routes)
1. #ip route 0.0.0.0 0.0.0.0 188.8.131.52 0
2. #ip route 0.0.0.0 0.0.0.0 184.108.40.206 0
So there are two default routes, both having administrative distance as 0.
My question is
1. Will the routing occur through both the ISP Defult Gateways?
2. Will both the bandwidths be summed up to 1 mbps (512 kbps + 512 kbps).
Please tell my planning is ok or you suggest some thing different.
Thanx for your help.
