I'm not an I2C expert (I should be though; used it a lot ages ago), but is there confusion here between the address of the component itself that you set in Platform Designer (in the base address column) vs. an address on the I2C bus? You can set the base address of a component to anything in the address space of whatever host you connect the agent to, but that's separate from addressing components on the I2C bus itself.

It's not about setting a salve address, but the issue is while reading the slave address from the Host processor.

I can read the right slave address nevertheless there is some unknow address is also coming along with the actual address.

My issue is with this unknow I2C slave address(that is 00) from the I2C Agent to Avalon-MM Host Bridge embedded IP.

please have a look into the attachment.
