Re: BGP Multihoming default-originate only setup

said by kamikatze:

I'm running OSPF, but i'm not redistributing any routes.
If there is no redistribution between BGP and OSPF, then how does OSPF know default route to the Internet? Using the default originate command?

3. How does your BGP-announced network look like on the Internet? A check on BGP looking glass (like one in this forum's FAQ) is a must to confirm.

5606 is my backup ISP (1mbps).
Assuming it is coming from Internet BGP Looking Glass, then I notice something questionable. The looking glass shows that your backup ISP is considered primary transit AS to reach your AS, which should not be happening. Using the ISP BGP Community, you should be able to tune this to make your primary ISP as the primary transit AS instead.
