unfortunatly nobody can  help you except yourself - first of all you need to invest a couple of days and read at least on cisco.com a couple of articales about BGP, after that you will able at least ask correct questions.

We can help you to configure BGP for a special usage but nobody will do the configuration for you.

hi kishor,

thanks for the link.

I want to setuop BGP with two ISP redundancy.

Whille reading document of BGP i came to know there are certain requirements to setup BGP

first is we have to have /24 pool from atleast one ISP and

AS number(is it private or public?)

I want to know what is it and why do we require this?

Hi Vishal,

You assumption is correct.

If you are connected to two ISP requirement is

> Portable IP assignment from local registry: apnic for example. Because even if your ISP has asigned /24 ip your second ISP will not announce it because AS Blacklisting issue.

> Public AS asignment from registry..i.e apnic. By default they provide 4 byte AS number so you can ask for 2 byte AS number if that is your requirement.

Hi,

as Mahesh has said, you need a public AS and a "PI" (Provider independet) subnet.

There is also a possibility to get from both ISP their PA subnets and with help of NAT get a failover configuration,
