OSPF / Static Route expert help, please

RouterOS Forwarding Protocols
1

Hello expert,

I have an project connect with ISP and BGP a new public ip subnet /24 IPv4, for example: 123.123.123.0/24

Currently Router 1:
eth1: static IP with ISP: 100.100.100.52/29 GW: 100.100.100.49
eth 11: new BGP IPv4: 123.123.123.1/24
eth12: private LAN: 192.168.1.1/24

I have connected a switch with eth11 for allocate our IPv4 to different servers, such as: 123.123.123.230/24 with GW: 123.123.123.1

It’s all currently work fine. But we have a new project from our customer, they want to make another router say: 123.123.123.242/24 . And want us to forward some /32 /30 /29 IPv4 to the customer behind this 123.123.123.242 router.
My question is:

  1. how to make it route those /32 /30 /29 to the customer behind that .242 router? Should I use OSPF , or any suggestion method ?
  2. does anyone have a online guideline can instruct me , because I actually is a beginner on this network.

I am really appreciate if any expert can guide me step by step , as I am already 2 weeks headache on it .

Thanks very much EXPERT !

Do you only have one router?
I suggest that you just use a static route.
Set the dst=123.123.123.X/29 (or whatever range you assign to the customer)
and set the gateway=x.x.x.x (the actual IP address of their router’s WAN interface facing you)

Oh - one more thing, you’ll want to configure arp=proxy-arp on ether11 if you’ve really configured that as a /24 interface, so that the rest of your hosts in the /24 can talk to the customer’s sub-set of your range.
