Hi Joshua!
How do you must advertise your routes to the ISP?
- If the ISP is able to configure static routes poiting to your network on
the peering router you can use static routes with AD (floating), or default
route, just in case.
- If the ISP is not able to configure static routes to your network we need
to know which other dynamic protocol it is able to configure for your
network besides BGP.
- If the ISP require you to use BGP (better way) you have many options to do
that like weight, local-preference, as-path etc...
Brgds,
Gabriel Nunes
