I'm assuming you have an AS number as well and are doing BGP with at least 1 other person upstream correct?

If so, you'll need to peer with the customers router (define the peer) and then you can choose what routes you send to his router. Some customers may want all routes, others may want only a default route and then others still want some mix in between. After you are peered with them you will receive their /22 from them. You then get to decide if you want to pass that route along to your upstreams. You may need them to adjust any filters they have set on you from their side to make sure it is repeated correctly out to the greater Internet.

Here in the US it common for the very large ISPs to have basically 3 sets of routes they send to their customer peers. All Internet routes, Default route only, Default route and routes local to the ISP only.

Hi
thanks for the answer.
I do the peering and work (i see his prefix) but I can't propagate to his router the full table. He has in bgp router 2 ISP so I must propagate tje full table right?
if I try to update the route table router is freezing and i can't ping it. I must disable and enable our peering.

No. Read the above post again.

Not enough information. By freezing do you mean it actually locks up and needs to be reloaded or is just unreachable?

....

Why don't you diagram up what you want are trying to do and we can get you there. Right now your description is too vague.

Add a peer at bgp menu and setup dedicated route filter for your customer and prefix, everything will be worked.
