Well, the RFC says: To simplify transition, this document assumes that an Autonomous System could start using a 4-octet AS number only after all the BGP speakers within that Autonomous System have been upgraded to support 4-octet AS numbers.
I'm really unclear on what happens if you enable it on a few routers and its not supported on others within an AS. The RFC isn't really clear on the issue in the case where your AS is two-octet compatible. In the case when your AS number is not two-octet compatible obviously it should default to on (currently it doesn't; this is a bug). Anyway I set it to be an explicit decision to turn it on rather than force anyone who upgrades to test out untested corner cases. - Mark On Dec 29, 2007 10:41 AM, Kristian Larsson <[EMAIL PROTECTED]> wrote: > Why is this an option?
