Within the next 6 weeks I will need to route an additional block of IP's that are currently advertised with another AS. We have another reseller that currently has their own AS, /20 IP block, and circuits but will connect to us for bandwidth and ISP services in the near future.
What do you believe is the best migration path for us to route their IP's?
1.For us to advertise their AS on cutnight?
2. or advertise their IP's with our existing AS?
Of course, with either option I will need to coordinate with my upstream ISP's to accept my new advertisements.
Thanks for any thoughts or suggestions!
