ASN 4 bytes : How to calculate and configure it …

To begin : How to calculate the ASN 4 bytes we need to configure it ?

So : ASN-decimal = 197632.

197632 % 65536 = 3

And

197632 - (65536 * 3) = 1024

Ok. Now we can configure it on a Cisco router :

router bgp XXXX

nei 197.66.55.33 remote-as 3.1024

I let you go on the configuration as always it works.
