Cisco router needs 2 WAN IP ranges from one DSL line. How do I configure this?

Hi All

A client has an exisitng ADSL with a range of IPs. They needed to extend this range as they needed more IP addreses, so their ISP has assigned and additional range in a different subnet to their ADSL too.
So they now have two ranges
82.x.x.x/28 & 212.x.x.x/28. on one ADSL.

How do I configure their Cisco router for both these WAN ranges simultaneously?

an option is to use a secondary ip address on the interface.

ip address
ip address secondary

These commands will put two ip addresses on the interface.

either by using the above solution
by creating sub interfaces i.i interface eth0.1 and interface eth0.2 and assign 1st subnet to the 1st interface and the 2nd subnet to the 2nd interface ..
