How to start outgoing VPN connection through a specific mikrotik port?

Question

VPN

Good afternoon! There is a router connected to two providers, both work using PPPoE technology, respectively, the interfaces are called pppoe-out1 and pppoe-out2 . Using the Distance parameter, the priority of using provider number 1 is configured, that is, its distance is 1 and the second one is 2.
There is also an outgoing VPN connection pptp-out1. Like all other traffic, connection to an external VPN server is made through pppoe-out1, at least while provider #1 is running.
Question: how to force pptp-out1 to work through provider #2?

Answer 1

/ip route add dst-address=1.1.1.1 gateway=pppoe-out2

where 1.1.1.1 is the address of the pptp server
