                 Hello Tarig,

                 (Cc:ed to AFNOG list)

                 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
                 block, etc...

                 Any additional information you might have that would help 
us in
                 understanding your setup is welcome.

                 Thanks,

hi phil

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.
