I have a design question.
This network has a single /24 of IPV4 space. Let's pretend 10.10.10.0/24 is routable IP space for the sake of this discussion. I have attached a crude diagram of the setup.
My questions are.
1.I don't want to blindly (no BGP synchronization) advertise the block out the upstream.
2.How do I synchronize this if the transport link goes down, the /25 goes away, and the route is no longer advertised? How does aggreation in mikrotik work? If the BGP speaker sees the /25 in the routing table will that work with synchronization? If so, how?
My other alternative is to run a tunnel between DC 1 and DC 2 and run BGP across the tunnel as well.
My issue can be solved with having a /24 at the DC for servers and a /24 for the client side. This seems wasteful though.
How are others solving this type of an issue?
