dual WAN failover using BGP and static route on 1 LAN

RouterOS Forwarding Protocols
1

Case:I have a RouterBoard RB450 with 5 ports.
Ether 1: interface name VSAT, has a 1mbps link with IP. Address 83.229.126.17/29
Ether 2: interface name Fibre, has a 5mbps link with IP. Address 78.138.59.74/30
(The ip address at the teleport is 78.138.57.63/30)
Ether 3: interface name LAN, has the users directly connected with IP. Address 192.168.0.1/24.

I need a mechanism that will implement BGP between the router Ether 2 ( Fibre interface) and the teleport, in addition I need a static route with higher administrative Value so as long as the Ether 2 (Fibre) is up the BGP is up and all traffic route through it. But when BGP goes down with Ether 2(fibre) down. The static route take priority and all traffic are routed through the Ether11(VSAT). Kindly, let me know how go about configuring this thank you.

Thanks, but that’s what my ISP requested me to do, but anyway if you can provide me full details on alternative methods apart from pinging an internet IP and using two routes with the default route with lower administrative cost while the backup route. With higher administrative cost. Thank you

My ISP wants me to use BGP for the first link and static route for the second link. Thank you and the net watch tool, how do I configure it ?thank you

10.0.0.1 is my directly connected IP address neighbor for the default route to the internet.

172.16.0.1 is an IP address out on the internet that I want to get to only from the provider.

If the address above goes down, I will disable the "Default Routes" routes and follow the other default route

in the OSPF network.
