Assuming we are talking about BGP here, use the local-as feature.

Hello Mr. P. dath,

As you suggested in above link according to this we can configure only one AS on Cisco 2811 Router.

But we want to configure both AS on cisco 2811 Router.

Let me present a more comprehensive example.

First choose one AS to be your primary.

router bgp 10385

Now add some neighbour lines to present yourself as a different AS when taking to the other ISP.

  neighbour x.x.x.x local-as 48174

This is the only way to make a single router appear to look like two (or more) different AS systems.
