Re: BGP CASE [7:30620]
That's easy you can give your client one CIDR block and have him advertised this CIDR block to you. You will not have to do anything as you could have aggregrated the CIDR block supernet and advertised it to your upstream providers like Sprint , ATT etc. regards, suaveguru --- Jason wrote: If the client wants to use YOUR address block... this is probably the easiest $$$ you can earn... :-)) Tough luck to him though Ismail M Saeed wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]...

For multihoming to work, you need to advertise both the aggregate and the more-specific, while the other provider advertises the more-specific of your address space. It's also a good idea that all of these policies are recorded in a routing registry. Otherwise, other providers may generate filters that do not consider the multihoming structure.

Thanks and best regards A good first start would be to examine your customer's and your routing policies as recorded in the RIPE routing registry. The customer presumably already advertises its prefixes to other AS, and it needs to do the same to you. Assuming the customer's goal is to gain additional availability, you certainly need to readvertise those prefixes to your upstreams. If you have other customers that default to you, those connections need no changes.

Re: BGP CASE [7:30620]
I'm afraid this is turning into one of those operational realities where your best course of action is hiring a competent consultant to take you through the planning and implementation. Some of the issues that will need to be examined include: 1. Are you, the other ISP, both, or neither designated by RIPE NCC as Local Internet Registries? At least one LIR will have to work with the RIPE NCC. 2. I'm troubled by your repeated use of the term class, which has no place in discussions of Internet routing, and the term owned with relation to them. The terms prefixes and allocation (the latter versus assignment) MUST be understood here. If all the ISPs involved don't understand them fully, they can very well produce designs in which RIPE NCC won't allocate more address space in the future. 3. There's no discussion of aggregation requirements and the need of a multihoming policy that advertises some more-specifics. 4. It's unclear if a link failure should cause the complete shift of advertised prefixes. Would normal BGP suffice, or does one ISP need to use the Cisco conditional advertisement feature? 5. The coordination can't just be with RIPE or the relevant LIR; it has to involve the other ISP as well. If both ISPs don't agree to advertise pieces of each others' address spaces, and/or don't register policies in the RIPE NCC routing registry that reflects this, higher-level providers that generate filters from the routing registry may very well refuse some of your routes, the customer's routes, etc. You'll want to read all relevant RIPE NCC documents on multihoming and AS allocation policy. They do have classes that can help in part of this. Consider attending the RIPE meeting in Amsterdam later this month and meeting some of the key people -- you might get enough help informally to be OK. Thx for your fast reply Actually this customer has two links, one to me and the second to another ISP. Also he uses some classes owned by me and other classes owned by the other provider. The case is he needs to BGP peer with me and with the other provider and to advertise the whole classes (owned by me and the other provider) to me and the other provider. In case one of the links failed he will still get his all classes from the other provider So can u please advise what to do with Ripe to achieve this?
