I have 2 ISP and I want to implement Dual-Wan with Load Balance and Failover. I have no idea how to implement it without affecting the routing configuration when the ppoe starts changing IP address. Is there a way that can automatically change the ip address from the PPOE?
Your post is confusing already.
You really need to have a plan and a firm grip on the details of the requirements.
a. identify all user(s)/device(s), groups of users and devices (including admin)
b. identify all the traffic flows they will need.
c. draw a network diagram detailing ISP connection, equipment and desired subnet flow.
For example your title says PCC and then your text says primary says pcc and failover, two slightly conflicting statements.
Help will come but only when you dont have a vague notion of what you want… nail down the requirements, the config will come so much more easily afterwards.
