I need help in configuring HA/load balance from Site A to Site B. Site A is the PRODUCTION and Site B is the BACKUP SITE. We have lease two Private line with two different providers running different speed. I need to configure Load Balance from Site A to Site B and vice-versa if possible, but i am more concert Site A to Site B.
We have Cisco 3850 on Site A, and two interfaces connected to each ISP. Site B, we have Cisco 3750, and two interfaces connected to each ISP as illustrated.
ISP #1 is live with IP 10.10.10/32 passing all traffic between two site as of now. Type of traffic is IP, UDP, TCP, HTTPS, and FTP.
I need help configuring ISP#2 . I need to use both private line at the same time for load balancing using these two switches, and automatically fail-over if one line is down.
I heard of Ether-channel, IP Based Policy, and Network load balancing. I need help with commands and scenario in the illustration below. I greatly appreciate with the right directions.
Thanks a lot.
