We've been recently assigned our own PI space and a 4byte AS number for our organization. We now have a requirement to peer with two ISP's for redundancy etc.
However, we currently have 2 7301 routers on the outside which don;t support 4byte AS numbers, the first ISP I need to peer with also does not provide current support for 4byte AS's.
I'm fine with traditional peering, acceptance of default and customer routes, RFC1918 filtering and path manipulation, however, how do I inform the Internet about our AS when nothing in the path seems to support it, I've read briefly about ASTRANS#23456 but can't find anything about configuring such a scenario, how will the Internet see my AS???
All assistance greatly received.
