This doesn't specify who is originating the BGP prefix. Both providers have to *route* it, of course.
We got this reply to a PI-space request for a customer that does not have his own ASN therefore ISPs would need to originate the route. Don't you think that this implies originating the prefix from two different ASes? (would appear when doing "sh ip bgp incons").
Yes. But this would not be any different from getting a PI space and announcing it inconsistently, that is, originating it from both ISPs.
Which is not a good practice in any case - I agree on that.
What is a good practice for small company who needs: 1. Small ammount of ip addresses (about /24) 2. Multihoming ? -- Regards, Vladimir.
