We already applied to AfriNIC, they allocated to us /18 ipv4 we're using two ISPs to connect to our customers and the same time we're using these ISPs for the Internet.
The ISP using tunnel layer 3. For customer sites to reach our NOC they need next hop to the ISP routers which we do not have a control.

Can you be a bit more specific about your network design ?
As I understand it, you have multiple sites, which can be connected
to different ISPs. As a result, your IP addressing plan is dependent
on the IPs that the local ISP will allocate to your site/customer --
is this correct ?
I'm not sure what you call a Virtual Network Environment, but I can
think of several methods, depending on how much control you have over
the local site -- from using VPNs (Virtual Private Network), or "tunnels"
over the existing infrastructure, and deploy your own IP addressing
scheme over that, to applying to Afrinic to get your own IP address
Any additional information you might have that would help us in
understanding your setup is welcome.
