Hi,

My curent requirement:-

Single Router at our premises - connected to Two ISP with two serial ports.

Looking for auto failure with BGP Multi homing in this scenario.

Do we need Public/Private AS in this requirement at our own permises.

Warm Regards!

Hello Mirza,

if you are an enterprise, depending on your needs a setup using a private AS number and NAT with two pools one from each ISP can be enough.

see the following document

http://www.cisco.com/en/US/tech/tk648/tk361/technologies_white_paper09186a0080091c8a.shtml

If you need an active/active solution probably you will need your own public AS number and your own address space.

a simple example of BGP multihoming
