Ebgp multi-hop is a great idea. Have others seen this done for non-bandwidth customers? ...a 'bgp-only' service...?... ...catalog that right along with v6 and multicast tunnels... ----- Original Message ----- From: Joe Maimon <jmaimon@ttec.com> To: Jason Biel <jason@biel-tech.com> Cc: nanog@nanog.org <nanog@nanog.org> Sent: Fri Feb 06 13:13:14 2009 Subject: Re: One /22 Two ISP no BGP Jason Biel wrote:

Charles,

As I mentioned earlier, you'll want to have one provider announce the /22 unweighted and the other announce it weighted. Just pick the better of the two providers as the primary. Don't base it soley off bandwidth, but check your SLA and any recent outage occurances.

Traffic will flow in via the primary until that link to you drops, the provider will remove the route, and traffic will come in the back up route.

Perhaps ebgp-multihop with this ISP's upstream provider might offer you an advantage combined with this approach. Probably worth a try.

I'll explain. We are a small ISP on a very remote Island. We have a /22 from ARIN. We have a 20mbits pipe from ISP1 and 20mbits from ISP2.

They are the only two we can get bandwidth.

So we are stuck with ISP1 that doesn't support BGP.

I want to advertise my /22 to two different ISP on different POP.

I can't use BGP as ISP1 doesn't support it.

Any suggestions ?

Thanks, Charles
