Good morning, I’m trying to create a community rule using my AS: xxx, but my AS has 6 digits and Mikrotik only accepts 5 digits.
How should 266437: xxx
But Mikrotik will not accept.
How should I proceed?
FYI.. the BGP Community is a Label.. you can define it as you like… it is considered best practices to use one’s ASN as the first part of the tag, this way it is always unique.. but there is no rule which says it has to be this way… e.g. you can use 12345:111 and that would be valid too.
BGP communities are 32-bits long in total, so if you have a 32-bit ASN you can’t use the standard ASN:xxx community values.
Best bet until large BGP communities become useful is to use a private ASN for the first 16 bits, such as 65530:100 etc.
BGP Functionality must please increase soon. We also have an AS of 6 digits.
