RTR2---ISP2
RTR1 & RTR2 are connected by IBGP & OSPF. In addition, RTR1 & RTR2 each
have 2
EBGP links connecting to ISP1 & ISP2 respectively.
RTR1 & RTR2 - AS3
ISP1 - AS1
ISP2 - AS2
RTR1, Eth0:- 172.16.3.1/24
RTR2, Eth0:- 172.16.3.2/24
Host A - 172.16.3.3/24
ISP1 has been assigned the address block 201.50.13.0/24, ISP2 has been
assigned
the address block 200.100.30.0/24.
What I want to achieve is that the NAT will translate inside addresses
appropriately for each ISP's assigned address block.
The problem I am having is that since hostA's IP is being NAT, neither RTR1
nor
RTR2 have the NAT range in their Routing Tables, which means I can't
advertise the NAT range to ISP1 & ISP2 in BGP by "network x.x.x.x mask
y.y.y.y". So what can I do to advertise these NAT ranges to ISP1 & ISP2??
Any help will be greatly appreciated.
Regards,
H.
