Hi sir,
the scenario:-
current:
ISP(10.1.1.1/30)----------10M static------------(10.1.1.2/30)customer|192.168.1.0/28|
*ISP operational IP 10.1.1.0/30 static route
*ISP assign block of /28 to customer for their own use. /28 is own by ISP.
New Setup:
ISP(ASN ISP)(10.1.1.1/30)--------10M BGP-------(10.1.1.2/30)(ASN CUSTOMER)|192.168.1.0/28|
*ISP and Customer run peering BGP-ok
*BGP run between ASN ISP and ASN Customer-ok
*Customer want to remain the IP block /28 (which is own by ISP) and advertised that IP block under ASN Customer-not ok.--- This is the issues. how can customer peer with ISP and at the same time advertised IP block thats belong to that ISP.
By right customer shall peer using their own ASN and own IP block which already register IRR. I dont know if this can be done via BGP peering, peer using own ASN and advertised IP block thats belong to other ISP.
I think this is not the right way of doing peering bgp. Comments and input very much appreciate. Thank you sir.
Thanks
