I have a juniper j2320 router with one service provider ABC on a serial port.Serial is configured with 10.72.15.1. Ethernet gig0/0 of this router is connected to my switch.This ethernet is configured with 10.72.4.0/24 subnet.
I have another service provider XYZ . This ISP has provided me a Maipu router which has two ethernet ports.One One ethrnet port has the ISP MPLS link on it .IP address on this ethernet is 10.225.162.173.The other ethernet has my lan pool 10.72.4.0/24 configured on it.
When my isp ABC link goes down. I remove the Juniper router ethernet gig0/0 cable and put it in my ISP XYZ's other ethernet port.
How do i make this failover automatic as currently i have to perform this manual shift?
