First to Mikrotik v7 for BGP, GRE Tunnel Router

RouterOS Beginner Basics
1

Hello, I’m first in mikrotik router os.

I installed x86 with Level5 License at my Dell Server.
I have 2x uplink from provider, each has 1x public ip and 1x downlink with Intel XL710 10GbE

I’m planning to connect BGP via GRE Tunnel to our provider, and announce our prefix.

We have 2 provider, one for anti-ddos provider with Inbound Only, another one is for Outbound Upstream.

I want to build my network like below:

  1. mikrotik establish BGP peer with anti-ddos provider via GRE Tunnel.
  2. mikrotik announce ip prefix to anti-ddos provider, and route.
  3. all outbound traffics should go to Outbound Upstream, linked directly via L3, nexthop is valid.

I tried to setup announce ipv4 but anti-ddos provider can’t see announcement.

Where do we need to find docs for them?

We already done with BGP peering and GRE Tunnel.

We need guide for PBR(Dynamic Source Routing) and ipv4 announcement.

almost of guides were written for Mikrotik Router v6

Thank you.
