Dear Experts,
We are at present using VSNL internet iP addresses and recently purchased APNIC Internet IPs which is made live via Airtel internet Link.
Now we want to migrate all VSNL IPs with APNIC IP addresses and finally terminate Airtel Internet link and VSNL IPs.
The proposed solution is shown in the diagram.
Now for the migration purpose, we need to make both Interent IPs (VSNL and APNIC IPs ) live. So need to configure NAT of Single Private iP address to be NAT with two different IP address as shown in diagram.
1. Can you suggest how it will be?
2. or How can I use both internet IP pool live at a time?
Thanks in advance.
Regards
Dipesh

Hi,
If the switch is Layer3 and you could run EIGRP routing on two CEs and switch. Then inject static default route from both CEs to EIGRP by redistributing. And L3 switch could do load-balancing. On CEs configure NAT overload.
