BGP AS no configuration

[kamlesh yadav]

Dear All,

we have 3845 routers with internet service providers connected on it.we have configured router bgp 2.xxx as our AS.

What is the concept behind router bgp 2.xxx with ISP?????

Hello,

Your ISP is assigning you a 4B ASN - that is what you see here. The ASN in linear format would be 65536*2+XXX, however, using the asdot format (2B.2B) is more convenient. There is nothing special with it, just make sure your IOS already supports 4B ASNs.

Best regards,

Peter

Thanks Peter for your prompt response,

I got the idea behind this configuration.If i have ASN as 131142,what will be its value in ASDOT and ASPLAIN format???

Hi,

it should  be 2.70 in dot format because 131142 is 00020046 in hex which gives 0002.0046 in hex which gives 2.70 in decimal.
